Selfassembly Preparation, Structure and Electrochemistry of Binuclear Complex [Cu2(TS)(H2O)]·H2O

The binuclear complex Cu 2(TS)(H 2O)]·H 2O, where TS donates the binuclearing ligand derived from the schiff base N,N'_bis(3_carboxylsalicylidene)trimethylenediamine, was obtained through the selfdecomposition of mononuclear complex Na 2CuTS·H 2O in the methanol/water. Complex crystals in the monoclinic system, space group P2 1/C, the lattice parameters are a =0.80830(16) nm, b =1.7079(3)nm, c =1.4073(3)nm, β =105.08(3)°, V =1.8654(6)nm 3 , Z =4 with R =0.0644. The title complex is made of binuclear units, in which two copper atoms are bridged by two phenolic oxygen atoms. Two copper atoms are separated by 0.29832(15)nm. The geometry of two coppers of complex is different from each other. The electrochemistry of the complex was examined and discussed on the basis of the molecular structure and electrochemistry of the mononuclear complex.
