Abstract top

The asymmetric unit of the title CdII complex, [Cd(C8H5O3)2(C6H6N2O)2(H2O)]·H2O, contains two 4-formylbenzoate (FB), two isonicotinamide (INA) ligands, one coordinated and one uncoordinated water molecule; the FB ions act as bidentate ligands. The coordination number of the Cd(II) atom is seven within a CdO5N2 donor set. Intramolecular O-H...O hydrogen bonds link the uncoordinated water molecules to the carboxyl groups. The dihedral angle between the carboxylate groups and the adjacent benzene rings are 17.53 (13) and 16.55 (14)°. In the crystal structure, intermolecular O-H...O, N-H...O, N-H...N and C-H...O hydrogen bonds link the molecules into a supramolecular structure. The amide group of one of the INA ligands is disordered over two orientations, with an occupancy ratio of 0.759 (3):0.241 (3).

Comment top

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.

In the monomeric title complex, (I), the CdII ion is surrounded by two formylbenzoate (FB) and two isonicotinamide (INA) ligands and one water molecule. The FB ions act as bidentate ligands, while the INA ions are monodentate ligands. The structures of similar complexes of ZnII ion, [Zn2(C10H14N2O)2(C7H5O3)4].2H2O, (II) (Hökelek & Necefoğlu, 1996) and [Zn(C9H10NO2)2(C6H6N2O)(H2O)2], (III) (Hökelek et al., 2009) have also been determined.

In the title compound (Fig. 1), the average Cd—O bond length (Table 1) is 2.4175 (13) Å and the Cd atom is displaced out of the least-squares planes of the carboxylate groups (O1/C1/O2) and (O3/C9/O4) by 0.1556 (2) Å and -0.0577 (2) Å, respectively. The dihedral angle between the planar carboxylate groups and the adjacent benzene rings A (C2—C7) and B (C10—C15) are 17.53 (13)° and 16.55 (14)°, respectively, while those between rings A, B, C (N1/C17—C21) and D (N3/C23—C27) are A/B = 7.05 (6), A/C = 69.34 (6), A/D = 66.49 (6), B/C = 68.78 (6), B/D = 73.54 (6) and C/D = 87.43 (5) °. The two four-membered rings, (Cd1/O1/O2/C1) and (Cd1/O3/O4/C9), are oriented at a dihedral angle of 20.06 (6)°. The intramolecular O—H···O hydrogen bonds (Table 2) link the uncoordinated water molecule to the carboxylate groups. In (I), the O1—Cd1—O2 and O3—Cd1—O4 angles are 52.91 (4) and 53.96 (4) °, respectively. The corresponding O—M—O (where M is a metal) angles are 58.3 (3)° in (II), 60.03 (6)° in (III) and 55.2 (1)° in [Cu(Asp)2(py)2] (where Asp is acetylsalicylate and py is pyridine) [(IV); Greenaway et al., 1984].

In the crystal structure, intramolecular O—H···O and intermolecular O—H···O, N—H···O, N—H···N and C—H···O hydrogen bonds (Table 2) link the molecules into a supramolecular structure, in which they may be effective in the stabilization of the structure.

Experimental top

The title compound was prepared by the reaction of 3CdSO4.8H2O (3.85 g, 5 mmol) in H2O (25 ml) and INA (1.22 g, 10 mmol) in H2O (40 ml) with sodium 4-formylbenzoate (1.72 g, 10 mmol) in H2O (50 ml). The mixture was filtered and set aside to crystallize at ambient temperature for several days, giving colorless single crystals.

Refinement top

Atoms H8 and H16 (for methine) and H91, H92, H101 and H102 (for H2O) were located in difference Fourier map and refined isotropically, with restrains of O9—H91 = 0.894 (15), O9—H92 = 0.875 (16), O10—H101 = 0.880 (16) and O10—H102 = 0.864 (18) Å and H91—O9—H92 = 106 (2) and H101—O10—H102 = 106 (3) °. The remaining H atoms were positioned geometrically with N—H = 0.86 Å (for NH2) and C—H = 0.93 Å for aromatic H atoms and constrained to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C,N). The O8, N4, H4A and H4B atoms are disordered over two orientations. During the refinement process, the disordered O8, N4, H4A, H4B and O8B, N4B, H4B1, H4B2 were refined with occupancies of 0.759 (3) and 0.241 (3), respectively.

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.
