Di-?-chlorido-bis-{[2-(8-quinol-yloxy)-acetato-?N,O,O]copper(II)}.

ABSTRACT: The title compound, [Cu(2)(C(11)H(8)NO(3))(2)Cl(2)], is a bicopper(II) complex. Each Cu(II) ion is five-coordinated by two O atoms and one N atom from the (8-quinol-yloxy)acetate ligand, and by two ?(2)-chloride ligands, thus exhibiting a distorted square-pyramidal CuCl(2)NO(2) coordination environment. Each (8-quinol-yloxy)acetate anion acts as a tridentate chelating ligand. In the crystal structure, adjacent quinolyl rings are involved in strong ?-? stacking inter-actions, with inter-planar distances of 3.549?(5) and 3.763?(5)?Å, thereby forming a two-dimensional planar network perpendicular to the ab plane. Furthermore, a weak inter-action [2.750?(4)?Å] is observed within these planes between one Cu(II) ion and a carboxyl-ate O atom from a ligand in an adjacent mol-ecule, which also contributes to the stability of the structure.

Each Cu(II) ion is five-coordinated by two O atoms and one N atom from the (8-quinol-yloxy)acetate ligand, and by two μ(2)-chloride ligands, thus exhibiting a distorted square-pyramidal CuCl(2)NO(2) coordination environment.
