The crystal structure of the title compound, [Cd(C₇H₅O₃)₂(C₆H₆NO)₂(H₂O)₂]·2[Cd(C₇H₅O₃)₂(C₆H₆NO)(H₂O)₂]·4H₂O, consists of two kinds of Cd^II complexes (A and B) and lattice water molecules. In complex A, [Cd(C₇H₅O₃)₂(C₆H₆NO)₂(H₂O)₂], the Cd^II cation is located on an inversion center and is coordinated by two salicylate anions, two nicotinamide (NA) ligands and two water molecules in a slightly distorted octahedral geometry. In complex B, [Cd(C₇H₅O₃)₂(C₆H₆NO)(H₂O)₂], the Cd^II cation is coordinated by two salicylate anions, one nicotinamide (NA) ligand and two water molecules in an irregular seven-coordinate geometry. There are extensive intramolecular O—H⋯O and weak C—H⋯O hydrogen bonds as well as extensive intermolecular O—H⋯O and N—H⋯O hydrogen bonding in the crystal structure. π–π stacking between the pyridine and benzene rings, between the benzene rings, between the benzene and pyridine rings and between the pyridine rings [centroid–centroid distances = 3.5989 (10), 3.6005 (10), 3.5800 (9) and 3.5205 (10) Å, respectively] further stabilize the crystal structure. A weak N—H⋯π interaction also occurs. One of the lattice water molecules is disordered over two positions with an occupancy ratio of 0.70:0.30.

Comment top

As part of our ongoing study on transition metal complexes of benzoate and nicotinamide, (NA), herein we report the synthesis and the structure of the title cocrystal diaquabis(salicylato-κO)bis(nicotinamide-κN) cadmium(II),(A), and diaquabis(salicylato-κ²O;O') (nicotinamide-κN)cadmium(II)dihydrate, (B).

The components of the title compound, [Cd(C₇H₅O₃)₂(C₆H₆NO)₂ (H₂O)₂], (A), and [Cd(C₇H₅O₃)₂(C₆H₆NO)(H₂O)₂].2(H₂O), (B), are mononuclear complexes. In complex A, the Cd^II cation is located on an inversion center and is coordinated by two salicylate anions, two nicotinamide (NA) ligands and two water molecules in a slightly distorted octahedral geometry (Fig. 1). In complex B, the Cd^II cation is coordinated by two salicylate anions, one nicotinamide (NA) ligand and two water molecules completing the irregular seven-coordination geometry (Fig. 1). There are extensive intramolecular O—H···O and weak C—H···O hydrogen bonding, beside of the extensive intermolecular O—H···O and N—H···O hydrogen bonding (Table 2) in the crystal structure.

The average Cd—O bond lengths (Table 1) are 2.3240 (12) and 2.4094 (12) Å for (A) and (B), respectively, and the Cd atoms are displaced out of the least-squares planes of the carboxylate groups: Cd1 atom for (O1/C1/O2) by 0.7250 (1) Å, Cd2 atom for (O6/C14/O7) and (O9/C21/O10) by -0.3415 (1) and -0.1105 (1) Å, respectively. In (B), the O6—Cd2—O7 and O9—Cd2—O10 angles are 53.45 (4) and 51.97 (4) °, respectively. The corresponding O—M—O (where M is a metal) angles are 52.91 (4)° and 53.96 (4)° in [Cd(C₈H₅O₃)₂(C₆H₆N₂O)₂(H₂O)].H₂O (Hökelek et al., 2009a), 60.70 (4)° in [Co(C₉H₁₀NO₂)₂(C₆H₆N₂O)(H₂O)₂] (Hökelek et al., 2009b), 58.45 (9)° in [Mn(C₉H₁₀NO₂)₂- (C₆H₆N₂O)(H₂O)₂] (Hökelek et al., 2009c), 60.03 (6)° in [Zn(C₈H₈NO₂)₂(C₆H₆N₂O)₂].H₂O (Hökelek et al., 2009d), 58.3 (3)° in [Zn₂(DENA)₂(C₇H₅O₃)₄].2H₂O (Hökelek & Necefoğlu, 1996) 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), C (C15—C20) and D (C22—C27) are 16.26 (17), 5.32 (16) and 3.53 (12) °, respectively, while those between rings A, B (N1/C8—C12) and C, D, E (N3/C28—C32), F (Cd2/O6/O7/C14), G (Cd2/O9/O10/C21) are A/B = 73.75 (4), C/D = 24.80 (6), C/E = 30.95 (6), D/E = 6.88 (6) and F/G = 25.62 (5) °.

In the crystal structure, extensive O—H···O and N—H···O hydrogen bonding (Table 2) may be effective in the stabilization of the structure. π···π contacts between the pyridine and benzene rings Cg2—Cg3ⁱ, between the benzene rings Cg3—Cg3ⁱ, between the benzene and pyridine rings Cg4—Cg5ⁱⁱ and between the pyridine rings Cg5—Cg5ⁱⁱⁱ, [symmetry codes: (i) -x, 1 - y, 1 - z, (ii) -x, 1 - y, -z, (iii) 1 - x, 1 - y, -z, where Cg2, Cg3, Cg4 and Cg5 are the centroids of the rings B (N1/C8—C12), C (C15—C20), D (C22—C27) and E (N3/C28—C32), respectively] may further stabilize the structure, with centroid-centroid distances of 3.5989 (10), 3.6005 (10), 3.5800 (9) and 3.5205 (10) Å, respectively]. A weak C-H···π interaction also occurs in the crsytal.

Experimental top

The title compound was prepared by the reaction of 3CdSO₄.8H₂O (1.283 g, 5 mmol) in H₂O (50 ml) and NA (1.220 g, 10 mmol) in H₂O (20 ml) with sodium salicylate (1.601 g, 10 mmol) in H₂O (200 ml). The mixture was filtered and set aside to crystallize at ambient temperature for two weeks, giving colorless single crystals.

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.
