Diaqua­bis(2-bromo­benzoato-κO)bis­(N,N-diethyl­nicotinamide-κN 1)nickel(II)

Abstract

In the monomeric centrosymmetric title NiII complex, [Ni(C7H4BrO2)2(C10H14N2O)2(H2O)2], the NiII ion is located on an inversion center. The asymmetric unit contains one 2-bromo­benzoate ligand, one diethyl­nicotinamide (DENA) ligand and one coordinated water mol­ecule. The four O atoms in the equatorial plane around the NiII ion form a slightly distorted square-planar arrangement, while the slightly distorted octa­hedral coordination is completed by two N atoms of two DENA ligands in the axial positions. The dihedral angle between the benzene ring and the attached carboxyl­ate group is 87.73 (15)°, while the pyridine and benzene rings are oriented at a dihedral angle of 42.48 (7)°. In the crystal structure, O—H(...)O hydrogen bonds link the mol­ecules into a two-dimensional network parallel to (10An external file that holds a picture, illustration, etc.

Comment

Transition metal complexes with biochemically active ligands frequently show interesting physical and/or chemical properties, as a result they may find applications in biological systems (Antolini et al., 1982). The structural functions and coordination relationships of the arylcarboxylate ion in transition metal complexes of benzoic acid derivatives change depending on the nature and position of the substituent groups on the benzene ring, the nature of the additional ligand molecule or solvent, and the medium of the synthesis (Nadzhafov et al., 1981; Shnulin et al., 1981). The nicotinic acid derivative N,N-diethylnicotinamide (DENA) is an important respiratory stimulant (Bigoli et al., 1972).

The structure determination of the title compound, (I), a nickel complex with two 2-bromobenzoate (BB), two diethylnicotinamide (DENA) ligands and two water molecules, was undertaken in order to determine the properties of the ligands and also to compare the results obtained with those reported previously.

Compound (I) is a monomeric complex, with the NiII ion on a centre of symmetry (Fig. 1). All ligands are monodentate. The four O atoms (O1, O4, and the symmetry-related atoms, O1', O4') in the equatorial plane around the Ni atom form a slightly distorted square-planar arrangement, while the slightly distorted octahedral coordination is completed by two N atoms of two DENA ligands (N1, N1') in axial positions (Table 1 and Fig. 1).

The near equality of C1—O1 [1.267 (3) Å] and C1—O2 [1.240 (3) Å] bonds in the carboxylate group indicates a delocalized bonding arrangement, rather than localized single and double bonds, and may be compared with the corresponding distances: 1.262 (3) and 1.249 (3) Å in [Mn(DENA)2(C8H5O3)2(H2O)2], (II) (Sertçelik et al., 2009a), 1.263 (4) and 1.249 (4) Å in [Ni(DENA)2(C8H5O3)2(H2O)2], (III) (Sertçelik et al., 2009b), 1.262 (5) and 1.257 (5) Å in [Co(DENA)2(C8H5O3)2(H2O)2], (IV) (Sertçelik et al., 2009c), 1.244 (4) and 1.270 (4) Å in [Co(NA)2(H2O)4](C7H4FO2)2, (V) (Özbek et al., 2009), 1.284 (2), 1.248 (2) and 1.278 (2), 1.241 (2) Å in [Zn(NA)2(C8H8NO2)2], (VI) (Tercan et al., 2009), 1.267 (3) and 1.258 (3) Å in [Ni(NA)2(C7H4ClO2)2(H2O)2], (VII) (Hökelek et al., 2009a), 1.263 (2) and 1.240 (2) Å in [Zn(DENA)2(C7H4BrO2)2(H2O)2], (VIII) (Hökelek et al., 2009b), 1.2611 (17) and 1.2396 (19) Å in [Mn(DENA)2(C7H4BrO2)2(H2O)2], (IX) (Hökelek et al., 2009c) and 1.2616 (17) and 1.2435 (18) Å in [Ni(DENA)2(C7H4ClO2)2(H2O)2], (X) (Hökelek et al., 2009d). In (I), the average Ni—O bond length is 2.0589 (15) Å and the Ni1 atom is displaced out of the least-squares plane of the carboxylate group (O1/C1/O2) by 0.291 (1) Å. The dihedral angle between the planar carboxylate group and the benzene ring A (C2-C7) is 87.73 (15)°, while that between rings A and B (N1/C8-C12) is 42.48 (7)°.

In the crystal structure, intermolecular O—H···O hydrogen bonds (Table 2) link the molecules into a two-dimensional network parallel to the (1 0 1). In addition, C—H···O hydrogen bonds are observed.

Experimental

The title compound was prepared by the reaction of NiSO4.6H2O (1.31 g, 5 mmol) in H2O (20 ml) and i>N,N-diethylnicotinamide (1.78 g, 10 mmol) in H2O (20 ml) with sodium 2-bromobenzoate (2.23 g, 10 mmol) in H2O (50 ml). The mixture was filtered and set aside to crystallize at ambient temperature for 2 d, giving blue single crystals.

Refinement

H atoms of water molecule were located in difference Fourier maps and refined isotropically. The remaining H atoms were positioned geometrically with C-H = 0.93, 0.97 and 0.96 Å for aromatic, methylene and methyl H atoms and constrained to ride on their parent atoms, with Uiso(H) = xUeq(C), where x = 1.5 for methyl H and x = 1.2 for all other H atoms.

Special details

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s 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 > σ(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.
