Synthesis and crystal structure of bis[2-[N-(2-chlorophenyl)formimidayl]-1-naphtholato]-(6Cl)copper(II)

Abstract

The title compound, bis[2-[N-(2-chlorophenyl)formimidayl]-1-naphtholato]-(6Cl) copper(II), [Cu(C(1)7H(1)1NOCl)(2)] (1) was synthesized and its crystal structure was determined. The Compound 1 is monoclinic, space group P2(1)/c with a = 9.146(3) Angstrom, b = 18.724(3) Angstrom, c = 16.230(2) Angstrom, beta = 96.46(1)degrees, V = 2761.8(11) Angstrom(3), Z = 4, D-c = 1.503 g cm(-)3, mu(Mo Kalpha) = 1.020 mm(-)1, R = 0.0606 for 2361 reflections [I > 2sigma(I)]. In the title compound, the Cu atom is coordinated by an N2O2 donor set from the imine-phenol ligand in a slightly distorted square planar coordination geometry, with the two phenolate O atoms being deprotonated. The Cu-O bond lengths are 1.878(4) and 1.889(4) Angstrom, the Cu-N bond lengths are 1.980(5) and 1.985(5) Angstrom. The angles O1-Cu-N1 and O2-Cu-N2 are 90.96(19) and 90.72(19)degrees, respectively.
