Synthesis and structure of complexes of some d metals with 10-(2-benzothiazolylazo)-9-phenanthrole (HL). Crystal and molecular structures of [CdL2] · DMF

The coordination compounds of cadmium(II), zinc(II), nickel(II), cobalt(II), and copper(II) with 10-(2-benzothiazolylazo)-9-phenanthrole (HL) were isolated in the crystalline state and studied. The crystal structure of the cadmium complex [CdL2] · DMF was determined by X-ray diffraction. The ligand is attached to cadmium in the form of anion functioning as an O,N,N-tridentate chelating ligand; this is accompanied by a change in its isomer form. The Cd configuration is a distorted octahedron. © 2013 Pleiades Publishing, Ltd.
