Summary: | A novel zinc compound with mixed ligands, Zn
(bipy)(bim)
·(ClO
·2H
O (
) (bipy = 4, 4′-bipyridine; bim = 2, 2′-biimidazole), was hydrothermally prepared and characterized by elemental analysis, IR spectroscopy, photoluminescence and single-crystal X-ray diffraction. Compound
is characteristic of an isolated structure with two five-coordinated zinc ions bridged by a bipy ligand to form a dumbbell-like motif. Compound
is of rhombohedral system, space group
-3 with

displays an emission band in the green region. In combination with the theoretical studies, it is believed that the emission must arise from the ligand-to-ligand charge-transfer (LLCT) transition. |
