Abstract top

The molecule of the title CuII complex, [Cu(C7H4ClO2)2(C6H6N2O)2], contains two 3-chlorobenzoate (CB) and two nicotinamide (NA) ligands; the CB act as bidentate ligands, while the NA are monodentate ligands. The resulting CuN2O4 coordination polyhedron is a considerably distorted octahedron. The dihedral angles between the carboxylate groups and the adjacent benzene rings are 17.92 (12) and 24.69 (16)°, while the two benzene rings and the two pyridine rings are oriented at dihedral angles of 52.20 (8) and 1.56 (6)°. In the crystal, N-H...N and C-H...O hydrogen bonds link the molecules into a three-dimensional network. The [pi]-[pi] contact between the benzene rings [centroid-centroid distance = 3.982 (2) Å] may further stabilize the crystal structure.

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, 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 CuII ion is surrounded by two 3–chlorobenzoate (CB) and two (NA) ligands. The CB act as bidentate ligands, while the NA are monodentate ligands. The structures of similar complexes of Zn(II) and Cd(II) ions, [Zn2(C10H14N2O)2(C7H5O3)4].2H2O, II, (Hökelek & Necefoğlu, 1996), [Zn(C9H10NO2)2(C6H6N2O).2H2O], III, (Hökelek, Dal et al., 2009) and [Cd(C8H5O3)2(C6H6N2O)2].H2O, IV, (Hökelek, Yılmaz et al., 2009) have also been determined.

In the title compound (Fig. 1), the Cu atom is displaced out of the least–squares planes of the carboxylate groups (O1/C1/O2) and (O3/C8/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 (C9—C14) are 17.92 (12)° and 24.69 (16)°, respectively, while those between rings A, B, C (N1/C15—C19) and D (N3/C21—C25) are A/B = 52.20 (8)°, A/C = 85.61 (7)°, A/D = 84.86 (7)°, B/C = 71.49 (7)°, B/D = 69.95 (6)° and C/D = 1.56 (6)°. The two four–membered rings, (Cu1/O1/O2/C1) and (Cu1/O3/O4/C8), are oriented at a dihedral angle of 12.07 (7)°.

In I, the O1–Cu1–O2 and O3–Cu1–O4 angles are 59.76 (5)° and 55.08 (5)°, respectively. The corresponding O–M–O (where M is a metal) angles are 58.3 (3)° in II, 60.03 (6)° in III, 52.91 (4) and 53.96 (4)° in IV, 53.50 (14)° in [Cu2(C8H5O3)4(C6H6N2O)4], V, (Sertçelik et al., 2013), 57.75 (2)° in [Cu(C7H4FO2)2(C7H5FO2)(C6H6N2O)2], VI, (Necefoğlu et al., 2011), 58.3 (3)° in [Cu(C7H5O2)2(C10H14N2O)2], VII, (Hökelek et al., 1996) 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 N—H···O and C—H···O hydrogen bonds (Table 1) link the molecules into a three–dimensional network, in which they may be effective in the stabilization of the structure. The ππ contact between the benzene rings, Cg2···Cg2i, where Cg2 is the centroid of the ring B (C9–C14) may further stabilize the structure, with Cg···Cg distance of 3.982 (2)Å. Symmetry code: (i) -x, 1-y, -z.

Experimental top

The title compound was prepared by the reaction of CuSO4.5H2O (1.25 g, 5 mmol) in H2O (50 ml) and NA (1.22 g, 10 mmol) in H2O (50 ml) with sodium 3–chlorobenzoate (1.79 g, 10 mmol) in H2O (100 ml). The mixture was filtered and set aside to crystallize at ambient temperature for one week, giving blue single crystals.

Refinement top

Atoms H2A, H2B, H4A and H4B (NH2 groups) were located in a difference Fourier map and refined isotropically. The remaining 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).

Special details top

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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.
