{2-[(3,5-Dichloro-2-oxidobenzyl-idene)amino-κN,O]-3-methyl-penta-noato-κO}(N,N'-dimethyl-formamide-κO)copper(II).

ABSTRACT: In the title compound, [Cu(C(13)H(13)Cl(2)NO(3))(C(3)H(7)NO)], the Cu(II) atom is coordinated in a slightly distorted square-planar geometry by two O atoms and one N atom from the tridentate chiral ligand 2-[(3,5-dichloro-2-oxidobenzyl-idene)amino]-3-methyl-penta-noate and by one O atom from dimethyl-formamide. In the crystal structure, the Cu atom forms contacts with Cl and O atoms of two units (Cu⋯Cl and Cu⋯O = 3.401 and 2.947 Å, respectively), thereby forming an approximately octa-hedral arrangement. A three-dimensional network is constructed through Cl⋯Cu, O⋯Cu, Cl⋯Cl contacts and C-H⋯O hydrogen bonds.

Project description:In the title compound, [Cu(C(16)H(11)Cl(2)NO(4))(H(2)O)]·1.5H(2)O, the Cu(II) atom is coordinated by two O atoms and one N atom from the 2-[(3,5-dichloro-2-oxidobenzyl-idene)amino]-3-(4-hydroxy-phen-yl)propionate ligand, and by the O atom from a water mol-ecule in a square-planar coordination.
