In the crystal structure of the title CoII complex, [Co(C8H5O3)2(C10H14N2O)2(H2O)2], the metal centre is located on an inversion center and is coordinated by two 4-formyl­benzoate (FOB), two diethyl­nicotinamide (DENA) ligands and two water mol­ecules in a slightly distorted CoO4N2 octa­hedral geometry. In the crystal structure, O—H⋯O hydrogen bonds link the mol­ecules into infinite chains. π–π contacts between the parallel pyridine rings of neighboring DENA ligands [centroid–centroid distance = 3.652 (3) Å] further stabilize the crystal structure.

Comment top

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 cobalt complex with two formylbenzoate (FOB), 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 Co atom on a centre of symmetry. It contains two FOB, two DENA ligands and two water molecules (Fig. 1). All ligands are monodentate. The four O atoms (O1, O5, and the symmetry-related atoms, O1', O5') in the equatorial plane around the Co atom form a slightly distorted square-planar arrangement, while the slightly distorted octahedral coordination is completed by the two N atoms of the DENA ligands (N1, N1') in the axial positions (Table 1 and Fig. 1).

The near equality of the C1—O1 [1.262 (5) Å] and C1—O2 [1.257 (5) 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: 1.263 (4) and 1.249 (4) Å in [Ni(DENA)2(C8H5O3)2(H2O)2], (II), (Sertçelik et al., 2009a), 1.262 (3) and 1.249 (3) Å in [Mn(DENA)2 (C8H5O3)2(H2O)2], (III), (Sertçelik et al., 2009b), 1.256 (6) and 1.245 (6) Å in [Mn(DENA)2(C7H4ClO2)2(H2O)2], (IV), (Hökelek et al., 2008), 1.265 (6) and 1.275 (6) Å in [Mn(C9H10NO2)2(H2O)4]. 2(H2O), (V), Hökelek & Necefoğlu, 2007), 1.260 (4) and 1.252 (4) Å in [Zn(DENA)2(C7H4FO2)2(H2O)2], (VI), (Hökelek et al., 2007), 1.259 (9) and 1.273 (9) Å in Cu2(DENA)2(C6H5COO)4, (VII), (Hökelek et al., 1995), 1.279 (4) and 1.246 (4) Å in [Zn2(DENA)2(C7H5O3)4]. 2H2O, (VIII), (Hökelek & Necefoğlu, 1996), 1.251 (6) and 1.254 (7) Å in [Co(DENA)2(C7H5O3)2(H2O)2], (IX), (Hökelek & Necefoğlu, 1997), 1.278 (3) and 1.246 (3) Å in [Cu(DENA)2(C7H4NO4)2(H2O)2], (X), (Hökelek et al., 1997). This may be due to the intermolecular O—H···O hydrogen bonding of the carboxylate O atoms (Table 2). In (I), the average Co—O bond length is 2.105 (3) Å and the Co atom is displaced out of the least-squares plane of the carboxylate group (O1/C1/O2) by 0.768 (1) Å. The dihedral angle between the planar carboxylate group and the benzene ring A (C2—C7) is 4.02 (35)°, while that between rings A and B (N1/C9—C13) is 79.61 (14)°.

In the crystal structure, intermolecular O—H···O hydrogen bonds (Table 1) link the molecules into infinite chains (Fig. 2), in which they may be effective in the stabilization of the structure. The π-π contact between the DENA rings, Cg1—Cg1i [symmetry code: (i) 2 - x, 1 - y, -z, where Cg1 is centroid of the ring B (N1/C9—C13)] may further stabilize the structure, with centroid-centroid distance of 3.652 (3) Å.

Experimental top

The title compound was prepared by the reaction of CoSO4.H2O (1.73 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 red single crystals.

Refinement top

H atoms of water molecule and formyl group were located in difference Fourier maps and refined isotropically, with restrains of O5—H51 = 0.94 (4), O5—H52 = 0.92 (2) Å, H51—O5—H52 = 105 (3)° and Uiso(H) = 0.09 (2) and 0.075 (18) Å2 (for H2O); C8—H81 = 1.04 (6) Å and Uiso(H) = 0.086 (19) Å2 (for formyl group). 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 atoms, and x = 1.2 for all other H atoms.

Special details top

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.
