Structure and characterization of bis(N-p-chloro-phenyl-salicylideneaminate) Schiff base copper(II) complex: Cu[N-p-Cl-Ph-Sal]2

The crystal and molecular structure of the title compound has been determined by X-ray crystallography. It crystallizes in the monoclinic system, space group P2₁/c, with lattice parameters a = 13.678(3), b = 10.729(2), c = 8.1996(2) Å, = 98.96°, V = 1188.7(4) ų, and Z = 4. The crystal structure contains two centrosymmetric molecules of bis (N-p-chloro-phenyl-salicylideneaminate) Schiff base copper(II). Copper(II) ion is coordinated in a slightly distorted trans square-planar configuration, the distortion consisting of a reduction of the N–Cu–O angle with the chelate rings from the ideal value of 90°. The p-chlorophenyl rings with salicylidene moieties form a dihedral angle of 38.96°.
