Diaqua­bis(N,N-diethyl­nicotinamide-κN 1)bis­(4-formyl­benzoato-κO 1)manganese(II)

Abstract

The title compound, [Mn(C8H5O3)2(C10H14N2O)2(H2O)2], contains one MnII atom lying on an inversion centre, two 4-formyl­benzoate and two diethyl­nicotinamide ligands and two coordinated water mol­ecules. All ligands are monodentate. The four O atoms around the Mn atom form a slightly distorted equatorial plane, while the distorted octa­hedral coordination is completed by the two N atoms in the axial positions. An intra­molecular O—H(...)O hydrogen bond occurs in the complex. In the crystal structure, O—H(...)O hydrogen bonds link the mol­ecules through an R 2 2(16) ring motif, forming a one-dimensional chain along the a axis. The π–π contact between the pyridyl rings [centroid–centroid distance = 3.629 (2) Å] may further stabilize the structure.

Comment

The structural functions and coordination relationships of the arylcarboxylates 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 molecules or solvents, and the medium of the synthesis (Nadzhafov et al., 1981; Shnulin et al., 1981). Transition metal complexes with biochemically active ligands frequently show interesting physical and/or chemical properties, and as a result, they may find applications in biological systems (Antolini et al., 1982). The structure determination of the title compound, (I), a manganese complex with two formylbenzoate (FOB) and 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 MnII atom lying on a centre of symmetry. It contains two FOB and two DENA ligands and two water molecules (Fig. 1). All ligands are monodentate. The four O atoms [O1, O5, and the symmetry-related atoms, O1ii, O5ii; symmetry code: (ii) 1 - x, 1 - y, 1 - z] around the Mn atom form a slightly distorted equatorial plane, while the slightly distorted octahedral coordination is completed by the two N atoms of the DENA ligands (N1, N1ii) in the axial positions (Table 1 and Fig. 1). The intramolecular O—H···O hydrogen bond (Table 2) results in the formation of a six-membered ring (Mn1, O1, O2, O5, C1, H52), which adopts envelope conformation with C1 atom displaced by -0.235 (3) Å from the plane of the other five atoms.

The near equality of the C1—O1 [1.262 (3) Å] and C1—O2 [1.249 (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: 1.256 (6) and 1.245 (6) Å in [Mn(DENA)2(C7H4ClO2)2(H2O)2], (II), (Hökelek et al., 2008), 1.265 (6) and 1.275 (6) Å in [Mn(C9H10NO2)2(H2O)4].2H2O, (III), (Hökelek & Necefoğlu, 2007), 1.260 (4) and 1.252 (4) Å in [Zn(DENA)2(C7H4FO2)2(H2O)2], (IV), (Hökelek et al., 2007), 1.259 (9) and 1.273 (9) Å in [Cu2(DENA)2(C6H5COO)4], (V), (Hökelek et al., 1995), 1.279 (4) and 1.246 (4) Å in [Zn2(DENA)2(C7H5O3)4].2H2O, (VI), (Hökelek & Necefoğlu, 1996), 1.251 (6) and 1.254 (7) Å in [Co(DENA)2(C7H5O3)2(H2O)2], (VII), (Hökelek & Necefoğlu, 1997), 1.278 (3) and 1.246 (3) Å in [Cu(DENA)2(C7H4NO4)2(H2O)2], (VIII), (Hökelek et al., 1997). This may be due to the intramolecular O—H···O hydrogen bond involving the carboxylate O atom (Table 2). In (I), the average Mn—O bond length is 2.183 (2) Å and the Mn atom is displaced out of the least-squares plane of the carboxylate group (O1, C1, O2) by -0.859 (1) Å. They are reported as -0.890 (1) Å in (II) and 2.185 (4) and 1.365 (3) Å in (III). The dihedral angle between the planar carboxylate group and the benzene ring A (C2–C7) is 3.0 (2)°, while that between rings A and B (N1, C9–C13) is 80.0 (1)°.

In the crystal structure, intermolecular O—H···O hydrogen bonds (Table 2) link the molecules through a R22(16) ring motif (Bernstein et al., 1995) to form a one-dimensional chain along the a axis (Fig. 2). The π-π contact between the pyridyl rings of DENA ligands, Cg1···Cg1iii [symmetry code: (iii) -x, 2 - y, 1 - z; where Cg1 is the centroid of ring B] may further stabilize the structure, with centroid–centroid distance of 3.629 (2) Å.

Experimental

The title compound was prepared by the reaction of Mn(SO4).H2O (1.69 g, 10 mmol) in H2O (50 ml) and DENA (3.56 g, 20 mmol) in H2O (15 ml) with sodium 4-formylbenzoate (3.44 g, 20 mmol) in H2O (50 ml). The mixture was filtered and set aside to crystallize at ambient temperature for several days, giving colourless single crystals.

Refinement

H atoms of water molecule and formyl group were located on difference Fourier maps and refined isotropically, with restrains of O—H = 0.95 (2) and C—H = 0.96 (2) Å. The remaining H atoms were positioned geometrically and refined as riding atoms, with C—H = 0.93 (aromatic), 0.97 (methylene) and 0.96 (methyl) Å, and with Uiso(H) = xUeq(C), where x = 1.5 for methyl H atoms and 1.2 for the other H atoms.
