摘要：

Two Cd(II) coordination compounds of a polydentate double Schiff base ligand 1,10-phenanthroline-2,9-dicarboxaldehyde-di-2-hydroxybenzoylhydrazone (L), [Cd(L)(dca)2]center dot 0.5H2O (dca = dicyanamide) (1) and [Cd(L)(SCN)2]center dot CHCl3 center dot DMF (DMF = N, N'-dimethylformamide) (2) were synthesized and structurally characterized. Compounds 1 and 2 crystallized in monoclinic system with the space group C2/C and P21/n, respectively. The ligand L, acting as a hexadentate chelate, is coordinated to one Cd(II) atom with rare hexagonal bipyramid coordination geometry in these two compounds. Fluorescent measurements showed that these two compounds all strongly emit at 570 nm with the excitation of ultraviolet light at 360 nm.
