| Abstract: | Interaction of cadmium(II) or zinc(II) acetate with 1,2-bis(4-pyridyl)ethane (bpe) in the presence of dioxime(1,2-cyclohexanedionedioxime = NioxH2 or diphenylglyoxime = dpgH2) resulted in three complexes with the compositions [Cd2(CH3COO)4(NioxH2)2(bpe)(H2O)2] (1), [Cd(CH3COO)2(bpe)(H2O)]n (2) and [Zn(CH3COO)2(NioxH2)(bpe)(H2O)]n (3), which were characterized by single-crystal X-ray diffraction, elemental analysis, IR, and luminescence spectroscopy. Dioxime-containing binuclear molecule 1 and 1D linear polymer 3 possess moderate luminescence properties, while the dioxime-free 1D polymer 2 demonstrates strong blue luminescence. |
