Abstract
Abstract
Three new compounds of zinc(II) and cadmium(II) with the ligand 4,4′-dimethoxy-2,2′-bipyridine (4,4′-dmo-2,2′-bpy), including cis-[Zn(4,4′-dmo-2,2′-bpy)2(SCN)2] (1), cis-[Cd(4,4′-dmo-2,2′-bpy)2(SCN)2] (2), and [Cd3(4,4′-dmo-2,2′-bpy)3(N3)5(OAc)]
n
(3), have been obtained as white single crystals by the branched tube method and characterized by elemental analysis, FT-IR and 1H, 13C NMR spectroscopy, and X-ray crystallography. Single-crystal structure analyses of the isostructural complexes 1 and 2 showed distorted octahedral geometry for zinc(II) and cadmium(II) with ZnN6 and CdN6 environments. Complex 3 reveals a rare coordination polymer containing octahedrally coordinated cadmium(II) expanding to chains by two different bridging modes, including Cd‒O‒C‒O‒Cd and Cd‒N‒Cd.
