双核配合物[Cu_2(TS)(H_2O)]·CH_3OH的自组装制备和晶体结构

The binuclear complex [Cu2(TS)(H2O)]·CH3OH , where TS denotes the binucleating ligand derived from the schiff base N,N′ bis(3 carboxylsalidene)trimethylenediamine, was obtained from the self decomposition of mononuclear complex Na2CuTS·H2O. It crystallizes in the monoclinic system, space group P21/c. The lattice parameters are a=11.935(2)?,b=15.667(3)?,c=11.621(2)?,β=111.60(3)°,V=2020.2(7)?3, Z=4 with R=0.0467. The structure is made of binuclear units, in which two copper atoms are bridged by two phenolic oxygen atoms. The "inside"copper atom is coordinated by two nitrogens, two phenolic oxygens in a planar coordination site, the copper atom deviates from the mean plane by 0.47?. The "outside"copper atom is five coordinated by two phenolic oxygen atoms?two equatorial carboxyl oxygen atoms and one axial water oxygen atom in a distorted tetragonal cone site, the copper atom is pulled out of the equatorial plane by 0.46?.
