In the title centrosymmetric binuclear CdII compound, [Cd2(C7H5O3)4(C6H6N2O)2]·4H2O, the six-coordinated CdII atom is chelated by the carboxyl­ate groups of the two 3-hy­droxy­benzoate (HB) anions; the two monomeric units are bridged through the two O atoms of the two carboxyl­ate groups. In the crystal, O—H⋯O, N—H⋯O and C—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional network. ππ Contacts between the pyridine rings and between the benzene rings [centroid-centroid distances = 3.770 (1), 3.769 (1) and 3.632 (1) Å] may further stabilize the structure.

As a part of our ongoing investigation on transition metal complexes of nicotinamide (NA), one form of niacin (Krishnamachari, 1974), and/or the nicotinic acid derivative N,N-diethylnicotinamide (DENA), an important respiratory stimulant (Bigoli et al., 1972), the title compound was synthesized and its crystal structure is reported herein.

The title compound consists of dimeric units located about an inversion centre and is made up of two Cd2+ cations, four 3-hydroxybenzoate (HB) anions, two isonicotinamide (INA) ligands and four uncoordinated water molecules (Fig. 1). Each CdII atom is chelated by the carboxylate O atoms of the two HB anions, and the two monomeric units are bridged through the two O atoms of the two carboxylate groups about the inversion center. The coordination number of each CdII atom is six. The Cd1···Cd1i distance is 3.818 (1) Å and O4-Cd1-O4i angle is 75.96 (4)° [symmetry code: (i) -x, -y+1, -z].

The Cd-O bond lengths vary from 2.3039 (11) to 2.5562 (11) Å with an average Cd-O value of 2.4033 (11) Å. The Cd atom is displaced out of the mean planes of the carboxylate groups, (O1/C1/O2) and (O4/C8/O5), by -0.0053 (1) and 0.0965 (1) Å, respectively. The O1-Cd1-O2 and O4-Cd1-O5 bond angles are 53.71 (4) and 54.59 (4) °, respectively. The corresponding O-M-O (where M is a metal) angles are 55.71 (5)° and 117.52 (4)° in [Cd2(MAB)4(NA)2(H2O)2] (Hökelek et al., 2010a), 55.96 (4)° and 53.78 (4)° in [Cd2(DMAB)4(NA)2(H2O)2] (Hökelek et al., 2010b), 52.91 (4)° and 53.96 (4)° in [Cd(FB)2(INA)2(H2O)].H2O (Hökelek et al., 2009a), 60.70 (4)° in [Co(DMAB)2(INA)(H2O)2] (Hökelek et al., 2009b), 58.45 (9)° in [Mn(DMAB)2(INA)(H2O)2] (Hökelek et al., 2009c), 60.03 (6)° in [Zn(MAB)2(INA)2].H2O (Hökelek et al., 2009d), 58.3 (3)° in [Zn2(DENA)2(HB)4].2H2O (Hökelek & Necefoğlu, 1996) [where NA, INA, DENA, HB, FB, MAB and DMAB are nicotinamide, isonicotinamide, N,N-diethylnicotinamide, 4-hydroxybenzoate, 4-formylbenzoate, 4-methylaminobenzoate and 4-dimethylaminobenzoate, respectively] and 55.2 (1)° in [Cu(Asp)2(py)2] (where Asp is acetylsalicylate and py is pyridine) (Greenaway et al., 1984).

The dihedral angles between the planar carboxylate groups and the adjacent benzene rings A (C2-C7) and B (C9-C14) are 10.25 (10) and 0.86 (11) °, respectively, while those between rings A, B, C (N1/C15-C19), D (N3/C21-C25), E (Cd1/O1/O2/C1) and F (Cd1/O4/O5/C8) are A/B = 3.13 (4), A/C = 73.27 (5), A/D = 77.13 (4), B/C = 70.25 (5), B/D = 74.27 (4), C/D = 9.07 (5) and E/F = 9.99 (4) °.

In the crystal, intermolecular O-H···O, N-H···O and C-H···O hydrogen bonds (Table 1) link the molecules into a three-dimensional network. The ππ contacts between the pyridine rings and between the benzene rings, Cg3—Cg4i, Cg1—Cg2ii and Cg2—Cg2iii [symmetry codes: (i) -x, -y+1, -z, (ii) x, +y-1, z, (iii) -x+1, -y+2, -z, where Cg1, Cg2, Cg3 and Cg4 are the centroids of the rings A (C2-C7), B (C9-C14), C (N1/C15-C19) and D (N3/C21-C25), respectively] further stabilize the crystal structure, with centroid-centroid distances of 3.770 (1), 3.769 (1) and 3.632 (1) Å, respectively.

Experimental top

The title compound was prepared by the reaction of 3CdSO4.8H2O (0.428 g, 5 mmol) in H2O (100 ml) and INA (1.220 g, 10 mmol) in H2O (50 ml) with sodium 3-hydroxybenzoate (1.601 g, 10 mmol) in H2O (100 ml). The mixture was filtered and set aside to crystallize at ambient temperature for five weeks, giving colourless block-like crystals.

Refinement top

Atoms H91, H92, H101 and H102 (for H2O) were located in a difference Fourier map and were freely refined. The remaining H-atoms were included in calculated postions and constrained to ride on their parent atoms: O—H = 0.82 Å, N—H = 0.86 Å, C—H = 0.93 Å, with Uiso(H) = k × Ueq(C,O,N), where k = 1.5 for OH H-atoms and k = 1.2 for all other H-atoms.

Special details top

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.
