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 -[Zn(4,4′-dmo-2,2′-bpy) (SCN) ] ( ), -[Cd(4,4′-dmo-2,2′-bpy) (SCN) ] ( ), and [Cd (4,4′-dmo-2,2′-bpy) (N (OAc)] ( ), have been obtained as white single crystals by the branched tube method and characterized by elemental analysis, FT-IR and H, C NMR spectroscopy, and X-ray crystallography. Single-crystal structure analyses of the isostructural complexes and showed distorted octahedral geometry for zinc(II) and cadmium(II) with ZnN and CdN environments. Complex 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.
