Abstract

A new centrosymmetric trinuclear Zn(II) complex [Zn₃L ₂(CH₃COO)₄] (1) has been synthesized by the reaction of Zn(CH₃COO)₂2H₂O with a tridentate N,N,O-donor Schiff base ligand HL [C₅H₄NC(CH ₃)=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(II) centers are in two different coordination environments. Two terminal Zn(II) centers adopt a distorted square-pyramidal geometry leaving the central Zn(II) in a distorted octahedral environment. Two adjacent metal centers are connected through single µ₂-phenolato as well as double µ-acetato-O,O' syn-syn bridges. Fluorescence properties of the complex as compared to the ligand indicate that the former can serve as a potential photoactive material. © 2009 Verlag der Zeitschrift für Naturforschung.
