(2,2'-Biquinoline-[bold kappa]2N,N')dichloropalladium(II), -copper(II) and -zinc(II)

Abstract: In the three title complexes, namely (2,2'-biquinoline-[bold kappa]2N,N')dichloropalladium(II), [PdCl2(C18H12N2)], (I), and the corresponding copper(II), [CuCl2(C18H12N2)], (II), and zinc(II) complexes, [ZnCl2(C18H12N2)], (III), each metal atom is four-coordinate and bonded by two N atoms of a 2,2'-biquinoline molecule and two Cl atoms. The PdII atom has a distorted cis-square-planar coordination geometry, whereas the CuII and ZnII atoms both have a distorted tetrahedral geometry. The dihedral angles between the N-M-N and Cl-M-Cl planes are 14.53  (13), 65.42  (15) and 85.19  (9)° for (I), (II) and (III), respectively. The structure of (II) has twofold imposed symmetry.

Formula: [PdCl2(C18H12N2)], [CuCl2(C18H12N2)] and [ZnCl2(C18H12N2)]
