| Abstract: | A new hexanuclear cadmium(II) complex of Cd6(pyim)4(Hpyim)6(sal)4 (Hpyim = 2-pyridylbenzimidazole, H2sal = salicylic acid) (1) has been synthesized under hydrothermal condition and characterized by element analysis, FT-IR spectroscopy and luminescent analysis. X-ray crystallographic studies reveal that complex 1 displays a novel hexanuclear unit in which six cadmium ions are bridged by deprotonated salicylic and pyridylbenzimidazole ligands. In 1, the hexanuclear units are further assembled into a 3D supramolecular framework by hydrogen bonding, π-π and C−H?π stacking interactions. In the solid state, complex 1 shows blue photoluminescent property at room temperature. |
