The title compound, [Cu(C7H4ClO2)2(C10H14N2O)2(H2O)], has twofold symmetry with the CuII cation and the O atom of the coordinating water mol­ecule located on the axis. The CuII cation is coordinated by two carboxyl­ate O atoms of chloro­benzoate (CB) anions, two N atoms of N,N-di­ethyl­nicotinamide (DENA) ligands and one water mol­ecule in a distorted N2O3 square-pyramidal geometry. The benzene and pyridine rings are oriented at a dihedral angle of 82.51 (6)°. In the anionic ligand, the carboxyl­ate group is twisted away from the attached benzene ring by 12.85 (11)°. In the crystal, O—H⋯O hydrogen bonds between the coordinating water mol­ecule and the carboxyl group link the complex mol­ecules into supra­molecular chains running along the c-axis direction.

Comment top

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 asymmetric unit of the title mononuclear CuII complex, (Fig. 1), contains one-half molecule, the CuII cation is located on a twofold rotation axis and is coordinated by carboxylate O atoms of two chlorobenzoate (CB) anions, N atoms of two N,N-diethylnicotinamide (DENA) ligands and by one water molecule, located on a twofold rotation axis, all ligands coordinating in a monodentate manner. The crystal structures of similar complexes of CuII, CoII, NiII, MnII and ZnII cations, [Cu(C7H5O2)2(C10H14N2O)2] (Hökelek et al., 1996); [Cu(C9H9O2)2(C10H14N2O)2(H2O)2] (Necefoğlu et al., 2011a); [Cu(C7H4FO2)2(C10H14N2O)2(H2O)2] (Necefoğlu et al., 2011b); [Co(C6H6N2O)2(C7H4NO4)2(H2O)2] (Hökelek & Necefoğlu, 1998); [Co(C9H9O2)2(C10H14N2O)2(H2O)2] (Necefoğlu et al., 2011c); [Ni(C7H4ClO2)2(C6H6N2O)2(H2O)2] (Hökelek et al., 2009a); [Mn(C9H10NO2)2(H2O)4].2H2O (Hökelek & Necefoğlu, 2007) and [Zn(C7H4BrO2)2(C6H6N2O)2(H2O)2] (Hökelek et al., 2009b) have also been reported. In the first copper(II) complex mentioned above the two benzoate ions coordinate to the CuII atom as bidentate ligands, while in the other structures all the ligands coordinate in a monodentate manner.

In the title complex, the four symmetry related O and N atoms (O1, O1a and N1, N1a) [symmetry code: (a) - x, 1 - y, z] in the equatorial plane around the CuII cation form a distorted square-planar arrangement, while the distorted square-pyramidal coordination is completed by the water O atom (O4) in the axial position.

The Cu—O bond lengths are 1.9346 (11) Å (for benzoate oxygen) and 2.238 (2) Å (for water oxygen), and the Cu—N bond length is 2.0303 (14) Å, close to standard values (Allen et al., 1987). The Cu atom is displaced out of the mean-plane of the carboxylate group (O1/C1/O2) by -0.1606 (1) Å. The dihedral angle between the planar carboxylate group and the adjacent benzene ring A (C2—C7) is 12.85 (11)°. The benzene A (C2—C7) and the pyridine B (N1/C8—C12) rings are oriented at a dihedral angle of 82.51 (6)°.

In the crystal, strong O—H···O hydrogen bonds (Table 2) link the water hydrogens to the carboxylate oxygens into infinite chains along the c-axis.

Experimental top

The title compound was prepared by the reaction of CuSO4.5H2O (1.25 g, 5 mmol) in H2O (100 ml) and diethylnicotinamide (1.78 g, 10 mmol) in H2O (20 ml) with sodium 3-chlorobenzoate (1.79 g, 10 mmol) in H2O (100 ml). The mixture was set aside to crystallize at ambient temperature for five days, giving blue single crystals.

Refinement top

Atom H41 (for H2O) was located in a difference Fourier map and was refined freely. The C-bound H-atoms were positioned geometrically with C—H = 0.93, 0.97 and 0.96 Å, for aromatic, methylene and methyl H-atoms, respectively, and constrained to ride on their parent atoms, with Uiso(H) = k × Ueq(C), where k = 1.5 for methyl 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.
