GRAPHICAL ABSTRACT
Abstract
A series of zinc(II) and cadmium(II) complexes, involving a combination of S–donor (xanthates and dithiophosphates) and N-donor (1,10-phen = 1,10-phenanthroline, 2,2′–bipy = 2,2′-bipyridine) ligands, of the composition [Cd(S2COnPr)2(2,2′-bipy)] (1), [Cd(S2COnPr)2(1,10-phen)] (2), [Cd(S2P(OEt)2)2(2,2′-bipy)] (3), [Cd(S2P(OEt)2)2(1,10-phen)] (4), [Zn(S2COnPr)2(2,2′-bipy)] (5), [Zn(S2COnPr)2(1,10-phen)] (6), [Zn(S2P(OEt)2)2(2,2′-bipy)] (7), and [Zn(S2P(OEt)2)2(1,10-phen)] (8) was prepared. The complexes (1–8) were characterized by elemental analysis and single-crystal X-ray analysis. X-ray structures revealed that the coordination geometries vary from octahedral (complexes 1–4), through square-pyramidal (complexes 5 and 6) to tetrahedral (complexes 7 and 8), depending on a combination of the central metal atoms and the corresponding S-donor and N-donor ligands. Similarities and discrepancies among the individual molecular structures as well as noncovalent contacts stabilizing crystal structures are discussed in more detail.
