Two new transition metal complexes based on chiral Schiff base ligand, namely Zn(L_1)_2(1) and Cd(L_2)2(2)(L 1=(R,E)-3-(2-hydroxy-3-methoxybenzylideneamino)propane-1,2-diol, L2=(R,E)-2-((2-hydroxy-1-phenylethylimino)methyl)-6-methoxyphenol), have been synthesized and characterized. Single-crystal X-ray diffractions reveal that both 1 and 2 crystallize in the same monoclinic space group C_2. 1 is four-coordinated, while 2 is six-coordinated. Complexes 1 and 2 show fluorescent emission at 479 and 580 nm, respectively. Moreover, 1 and 2 exhibit selective and sensitive recognition toward Zn~(2+)/Cd~(2+) ions in the methanol solution.
