Abstract

In the title complex, [Cu(C12H7BrClN2O)2], the CuII center is tetra­coordinated by two phenolate O and two azomethine N atoms from two independent bidentate 4-bromo-2-[(2-chloro-3-pyrid­yl)imino­meth­yl]phenolate (L) ligands. In the crystal structure, the CuII atom has a distorted square-planar coordination environment. The inter­planar dihedral angles between the benzene and pyridine rings in the individual ligands are 63.83 (4) and 54.43 (3)°, indicating the pyridine ring to have considerably weaker steric hindrance.

Comment

Phenoxy-imines are a versatile class of ligands that display a truly impressive range of diverse applications spanning from bioinorganic chemistry to coordination chemistry, chemical catalysis, and materials related applications (John et al., 2007). Due to their chelating ability and positive redox potential many copper(II) complexes are generally biologically active (Karmaka et al., 2007). As part of our ongoing research into the complexes between transition metals and phenoxy-imine ligands, we report here the synthesis and crystal structures of the title complex, bis{(E)-[4-bromo-2-((2-chloropyridin-3-ylimino)methyl-κN)] phenolato-κO1}copper(II) (Fig. 1).

In the asymmetric molecule unit of the title complex, the CuII center is tetracoordinated by two phenolic O and two azomethine N atoms from two ligand (L-) units and has a distorted square-planar coordination environment, which is similar to the salen-type bisoxime complexes (Dong et al., 2009a, Dong et al., 2009b). It was observed that all bond lengths are within normal ranges (Allen et al., 1987).

The interplane dihedral angles are found to be as follows: 63.83° between the phenyl ring (C2—C7) and pyridyl ring (N1/C8—C12), 54.43° between phenyl ring (C14—C19) and pyridyl ring (N3/C20—C24), indicating the pyridine ring having a considerable weaker steric hindrance. Besides, the dihedral angle between the coordination plane of O1—Cu1—N2 and O2—Cu1—N4 is 27.72 (3)°, indicating slight distortion toward tetrahedral geometry from the square planar structure.

Experimental

(E)-[4-Bromo-2-((2-chloropyridin-3-ylimino)methyl)]phenol(HL) was prepared according to previously reported procedure (Dong et al., 2009c). A blue solution of copper(II) acetate monohydrate (2.6 mg, 0.0013 mmol) in methanol (2 ml) was added dropwise to a pale-yellow solution of HL (8.1 mg, 0.0026 mmol) in methanol (4 ml) at room temperature. The color of the mixing solution turned to yellow immediately, then turned to brown slowly and allowed to stand at room temperature for several days. With evaporation of the solvent, dark-brown needle-like single crystals suitable for X-ray crystallographic analysis were obtained. IR: ν C=N, 1600 cm-1, ν Ar—O, 1242 cm-1, ν Cu—N, 445 cm-1 and ν Cu—O, 424 cm-1.

Refinement

Non-H atoms were refined anisotropically. H atoms were treated as riding atoms with distances C—H = 0.93 Å (CH), and Uiso(H) = 1.2 Ueq(C) and 1.5 Ueq(O).

Special details

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.
