Abstract

Abstract: A novel bis(phenoxo) bridged binuclear copper (Ⅱ) complex with dissimilar coordination environments was synthesized and characterized by spectroscopies and X-ray crystallography. It crystallized in the monoclinic system with space group C2/c, a=2.241 1 (2) nm, b=1.834 2 (2) nm, c=1.877 9(2) nm, β=122.861(2)°, V=6.484 3(11) nm³, Z=8. It consists of two unsymmetrical Cu(Ⅱ) centers bridged by two phenolic oxygen atoms to yield a Cu₂O₂ core with the Cu-Cu separation of 0. 310 2 nm, in which Cu1 and Cu2 ions exhibit distorted N₂O₃ and N₃O₂ square pyramidal geometries, respectively.
