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 coordi-nation 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?. 相似文献

过渡金属-碱土金属铜镁异双核配合物的合成、晶体结构和性质研究 总被引:2,自引:0,他引:2
The transition metal and alkaline earth metal heterobinuclear complex[CuMg(TS)(H2O)·H2O],where TS is the schiff base N,N′-bis(3-carboxylsalidene)trimethylenediamine, was synthesised and its crystal structure was determined by the single-crystal X-ray diffraction method at room temperature. It crystallizes in the monoclinic system, space group P21/n. The lattice parameters are a=12.041(2)?, b=14.736(3)?, c=12.062(2)?, β=118.00(3)°, Z=4 with R1=0.0364. The thermal property and EPR studies of the complex according to crystal structure are also investigated. CCDC: 182408. 相似文献
