چکیده
The title compound, C(19)H(10)F(5)NO(2), was synthesized by the 1:1 condensation of 2-methyl-8-hydroxy-quinaldine with penta-fluoro-benzaldehyde. It crystallizes with two almost identical mol-ecules in the asymmetric unit. The penta-fluoro-benzene ring is essentially coplanar with the quinoline ring, forming dihedral angles of 2.49 (17) and 8.72 (16)° in the two mol-ecules.

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 μ(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 str...
