摘要：

A new centrosymmetric trinuclear Zn(II) complex [ZnL3(CH3COO)(4)] (1) has been synthesized by the reaction of Zn(CH3COO)(2)center dot 2H(2)O with a tridentate N,N,O-donor Schiff base ligand HL [C5H4NC(CH3)=NC6H4(OH)] and systematically characterized by elemental analysis, FT-IR, UV/Vis and thermal methods. Single crystal X-ray structure analysis reveals that three Zn(H) centers are in two different coordination environments. Two terminal Zn(II) centers adopt a distorted square-pyramidal geometry leaving the central Zn(H) in a distorted octahedral environment. Two adjacent metal centers are connected through single mu(2)-phenolato as well as double mu-acetato-O,O' syn-syn bridges. Fluorescence properties of the complex is compared to the ligand indicate that the former can serve as a potential photoactive material.
