(Received 6 June 2013; accepted 7 June 2013; online 15 June 2013)

In the centrosymmetric dinuclear title compound, [Cd2(C7H4ClO2)4(C6H6N2O)2(H2O)2], the CdII atom is coord­inated by one N atom from one bridging nicotinamide ligand and one O atom from another symmetry-related bridging nicotinamide ligand, four O atoms from two 3-chloro­benzoate ligands and one water mol­ecule in an irregular geometry. The dihedral angles between the carboxyl­ate groups and the adjacent benzene rings are 6.98 (12) and 2.42 (13)°, while the benzene rings are oriented at a dihedral angle of 4.33 (6)°. Inter­molecular O—H⋯O, N—H⋯O and weak C—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional network. ππ inter­actions, indicated by short centroid–centroid distances [3.892 (1) Å between the pyridine rings and 3.683 (1) Å between the benzene rings] further stabilize the structure.

As a part of our ongoing investigations of 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, (I), consists of dimeric units located around a crystallographic symmetry center and made up of two Cd cations, four 3-chlorobenzoate (CB) anions, which act in bidentate modes, two nicotinamide (NA) ligands and two water molecules (Fig. 1). Both of the CdII centres are seven-coordinated, and the two monomeric units are bridged through the two nicotinamide (NA) ligands about an inversion center. The Cd1···Cd1a [symmetry code: (a) 1 - x, - y, 1 - z] distance is 7.1647 (3)Å. In the molecule, two Cd—O bond distances [2.4800 (13)Å and 2.5447 (15)Å] are significantly longer than the other four, and the average Cd—O bond length is 2.3798 (14)Å (Table 1). The Cd atom is displaced out of the least-squares planes of the carboxylate groups (O1/C1/O2) and (O3/C14/O4) by -0.2003 (1)Å and -0.3909 (1)Å, respectively.

The dihedral angles between the planar carboxylate groups and the adjacent benzene rings A (C2—C7) and C (C15—C20) are 6.98 (12)° and 2.42 (13)°, respectively, while those between rings A, B (N1/C8—C12) and C are A/B = 80.48 (7)°, A/C = 4.33 (6)°, B/C = 81.80 (7)°.

In (I), the O1-Cd1-O2 and O3-Cd1-O4 angles are 54.22 (4)° and 53.32 (5) °, respectively. The corresponding O—M—O (where M is a metal) angles are 57.75 (2)° in [Cu(C7H5O2F)(C7H4O2F)2(C6H6N2O)2], (II) (Necefoğlu et al., 2011a), 60.32 (4)° in [Co(C8H7O3)2(C6H6N2O)(H2O)2], (III) (Hökelek et al., 2010a), 59.02 (8)° in [Zn(C8H8NO2)2(C6H6N2O)2].H2O, (IV) (Hökelek et al., 2009a), 60.03 (6)° in [Zn(C9H10NO2)2(C6H6N2O)2(H2O)2], (V) (Hökelek et al., 2009b), 57.53 (5)°, 56.19 (5)° and 59.04 (4)° in [Zn(C8H7O3)2(C6H6N2O)2], (VI) (Hökelek et al., 2010b), 57.61 (8)° in [Mn2(C7H4O2Br)4(C6H6N2O)2(H2O)2], (VII) (Necefoğlu et al., 2011b) and 55.2 (1)° in [Cu(Asp)2(py)2] (where Asp is acetylsalicylate and py is pyridine) [(VIII); Greenaway et al., 1984].

In the crystal structure, intermolecular O—H···O, N—H···O and C—H···O hydrogen bonds link the molecules into a three dimensional network (Table 2), in which they may be effective in the stabilization of the structure. The π···π contacts between the pyridine rings and between the benzene rings, Cg2—Cg2i and Cg1—Cg3ii [symmetry codes: (i) 2 - x, - y, - z; (ii) 1 - x, 1 - y, 1 - z, where Cg1, Cg2 and Cg3 are the centroids of the rings A (C2—C7), B (N1/C8—C12) and C (C15—C20), respectively] may further stabilize the structure, with centroid-centroid distances of 3.892 (1)Å and 3.683 (1)Å, respectively.

Experimental top

The title compound was prepared by the reaction of 3CdSO4.8H2O (1.283 g, 5 mmol) in H2O (50 ml) and nicotinamide (1.220 g, 10 mmol) in H2O (50 ml) with sodium 3-chlorobenzoate (1.790 g, 10 mmol) in H2O (100 ml) at room temperature. The mixture was filtered and set aside to crystallize at ambient temperature for two weeks, giving colorless single crystals.

Refinement top

Atoms H61, H62 (for H2O) and H21, H22 (for NH2) were located in a difference Fourier map and were freely refined. The C-bound H-atoms were positioned geometrically with C—H = 0.93Å for aromatic H-atoms, and constrained to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C).

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.
