Crystal structure of bis­(μ-3-nitro­benzoato)-κ3 O,O′:O3 O:O,O′-bis­[bis­(3-cyano­pyridine-κN 1)(3-nitro­benzoato-κ2 O,O′)cadmium]

Abstract

The asymmetric unit of the title compound, [Cd2(C7H4NO4)4(C6H4N2)4], contains one CdII atom, two 3-nitro­benzoate (NB) anions and two 3-cyano­pyridine (CPy) ligands. The two CPy ligands act as monodentate N(pyridine)-bonding ligands, while the two NB anions act as bidentate ligands through the carboxyl­ate O atoms. The centrosymmetric dinuclear complex is generated by application of inversion symmetry, whereby the CdII atoms are bridged by the carboxyl­ate O atoms of two symmetry-related NB anions, thus completing the distorted N2O5 penta­gonal–bipyramidal coordination sphere of each CdII atom. The benzene and pyridine rings are oriented at dihedral angles of 10.02 (7) and 5.76 (9)°, respectively. In the crystal, C—H(...)N hydrogen bonds link the mol­ecules, enclosing R 2 2(26) ring motifs, in which they are further linked via C—H(...)O hydrogen bonds, resulting in a three-dimensional network. In addition, π–π stacking inter­actions between parallel benzene rings and between parallel pyridine rings of adjacent mol­ecules [shortest centroid-to-centroid distances = 3.885 (1) and 3.712 (1) Å, respectively], as well as a weak C—H(...)π inter­action, may further stabilize the crystal structure.

Chemical context  

In the last two decades, research on metal–organic frameworks (MOFs) has received considerable attention due to their extensive structural chemistry (Li et al., 2016  ) and their potential applications, including gas storage, nonlinear optics and ion exchange (Carlucci et al., 2003  ). In the syntheses of compounds having MOF structures, various carboxyl­ate ligands have been used (Li et al., 2004  ).

On the other hand, transition-metal complexes with biochemically active mol­ecules show inter­esting physical and/or chemical properties, through which they may find applications in biological systems (Antolini et al., 1982  ). Some benzoic acid derivatives, such as 4-amino­benzoic acid, have been extensively reported in coordination chemistry, as bifunctional organic ligands, due to the varieties of their coordination modes (Chen & Chen, 2002  ; Amiraslanov et al., 1979  ; Hauptmann et al., 2000  ).

The structure–function–coordination relationships of aryl­carboxyl­ate ions in ZnII complexes of benzoic acid derivatives change depending on the nature and position of the substituted groups on the benzene ring, the nature of the additional ligand mol­ecule or solvent, and the pH range and temperature of the synthesis (Shnulin et al., 1981  ; Nadzhafov et al., 1981  ; Antsyshkina et al., 1980  ; Adiwidjaja et al., 1978  ). When pyridine and its derivatives are used instead of water mol­ecules, the structure is completely different (Catterick et al., 1974  ).

The structures of some dinuclear complexes obtained from the reactions of transition metal(II) ions with nicotinamide (NA; C6H6N2O) and some benzoic acid derivatives as ligands, e.g. [Zn2(C7H4FO2)4(C6H6N2O)2]·C7H5FO2 [(II); Hökelek et al., 2009  ], [Cu2(C8H7O3)4(C6H6N2O)2(H2O)2] [(III); Hökelek et al., 2010  ], [Cu2(C8H5O3)4(C6H6N2O)4] [(IV); Sertçelik et al., 2013  ], [Mn2(C7H4BrO2)4(C6H6N2O)2(H2O)2] [(V); Necefoğlu et al., 2011  ] and [Cd2(C7H4ClO2)4(C6H6N2O)2(H2O)2] [(VI); Bozkurt et al., 2013  ], have been determined previously. In this context, we have synthesized the CdII-containing title compound, bis(μ-3-nitro­benzoato)-κ3 O,O′:O3 O:O,O′-bis­[bis­(3-cyano­pyridine-κN)(3-nitro­benzoato-κ2 O,O′)cadmium], [Cd2(C7H4NO4)4(C6H4N2)4], and report herein its crystal structure.

Structural commentary  

The asymmetric unit of the title complex contains one CdII atom, two 3-nitro­benzoate (NB) anions and two 3-cyano­pyridine (CPy) ligands. The two CPy ligands are monodentate (through the pyridine N atoms), while both NB anions act as bidentate ligands through their carboxyl­ate O atoms (Fig. 1  ). The centrosymmetric dinuclear mol­ecule is completed by application of inversion symmerty. The CdII atoms are bridged by the carboxyl­ate O atoms of one NB anions (O6 and O5) and its symmetry-related counterpart [symmetry code: (i) −x, −y + 1, −z + 1]. Hence, this carboxyl­ate group not only chelates to one CdII atom but also bridges two CdII atoms (Fig. 2  ). Thus, each CdII atom is surrounded by three NB anions and two CPy ligands. The overall coordination sphere of the CdII atom is defined by the bridging/chelating NB anions (O5, O5i and O6), one chelating NB anion (O1 and O2) and two 3-cyano­pyridine (CPy) ligands (N3 and N5), resulting in a distorted penta­gonal–bipyramidal environment. The five carboxyl­ate O atoms (O1, O2, O5, O5i and O6) of the three NB anions around the CdII atom form a distorted penta­gonal arrangement, with an average Cd1—O bond length of 2.42 Å (Table 1  ). The distorted penta­gonal–bipyramidal coordination is completed by pyridine atoms N3 and N5 of the CPy ligands at distances of 2.3186 (17) and 2.3435 (17) Å, respectively, in the axial positions (Table 1  ; Figs. 1  and 2  ). The Cd1 atom lies 0.1252 (1) Å above and 0.0326 (1) Å below of planar O1/O2/C1 and O5/O6/C8 carboxyl­ate groups, respectively. The Cd1(...)Cd1i separation in the binuclear mol­ecule is 3.9360 (15) Å and is comparable to the corresponding MM distances (M is a metal) in the structurally related transition metal(II) complexes [7.1368 (3) Å in (III), 4.1554 (8) Å in (IV), 7.180 (2) Å in (V) and 7.1647 (3) Å in (VI)]. The metal atoms are bridged by two NA ligand N and O atoms in (III), (V) and (VI), while they are bridged by two carboxyl­ate O atoms in (IV).

The O1—Cd1—O2 and O5—Cd1—O6 bite angles are reduced to 54.33 (5) and 53.47 (5)°, respectively. The corresponding O—M—O (M is a divalent metal) angles are 60.92 (12)° in (II), 53.50 (14)° in (IV), 57.61 (8)° in (V), and 54.22 (4) and 53.32 (5)° in (VI). The dihedral angles between the planar carboxyl­ate groups (O1/O2/C1 and O5/O6/C8) and the adjacent benzene [A (C2–C7) and B (C9–C14)] rings in the title structure are 17.18 (13) and 3.36 (12)°, respectively, while the benzene (A and B) and pyridine [C (N3/C15–C19) and D (N5/C21–C25)] rings are oriented at dihedral angles of A/B = 10.02 (7)°, A/C = 72.70 (7)°, A/D = 74.72 (7)°, B/C = 82.28 (7)°, B/D = 84.54 (8)° and C/D = 5.76 (9)°.

Supra­molecular features  

Intra­molecular C—Hcpy(...)Oc (cpy = cyano­pyridine and c = carboxyl­ate) and C—Hnb(...)Oc (nb = nitro­benzoate) hydrogen bonds (Table 2  ) link the cyano­pyridine and nitro­benzoate ligands to the carboxyl­ate O atoms.

The π–π contacts between parallel benzene rings and between parallel pyridine rings of adjacent mol­ecules, Cg1–Cg2i and Cg3–Cg4ii [symmetry codes: (i) −x + 1, −y + 1, −z + 1; (ii) −x, −y + 1, −z + 1; Cg1, Cg2, Cg3 and Cg4 are the centroids of the rings A (atoms C2–C7), B (C9–C14), C (N3/C15–C19) and D (N5/C21–C25)] may further stabilize the structure, with centroid–centroid distances of 3.885 (1) and 3.712 (1) Å, respectively. A weak C—H(...)π inter­action (Table 2  ) is also observed.

Refinement  

The experimental details including the crystal data, data collection and refinement are summarized in Table 3  . Aromatic H atoms were positioned geometrically, with C—H = 0.93 Å, and constrained to ride on their parent atoms, with U iso(H) = 1.2U eq(C). The maximum and minimum electron densities were found at 1.43 and 0.80 Å from atoms O2 and Cd1, respectively.

Synthesis and crystallization  

The title compound was prepared by the reaction of 3CdSO4·8H2O (0.64 g, 2.5 mmol) in H2O (50 ml) and 3-cyano­pyridine (0.52 g, 5 mmol) in H2O (50 ml) with sodium 3-nitro­benzoate (0.95 g, 5 mmol) in H2O (100 ml) at 333 K. The mixture was filtered and set aside to crystallize at ambient temperature for one week, giving colourless single crystals.

Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
