N-(邻氯苯甲酰基)-N＇-(2,3-二甲基苯基)硫脲合铜(I)二聚体配合物的合成与表征

Preparation and characterization of a new Cu(Ⅰ) dimer derived from the N-( o-chloro benzoyl)-N'-( 2,3-dimethyl phenyl)-thiourea

将CuCl2的二氯甲烷溶液缓慢倒入含有N-(邻氯苯甲酰基)-N'-(2,3-二甲基苯基)硫脲的乙醇溶液中,得到一个对称单元C32H30N4O2Cu Cl3S2·CH2Cl2的二聚物单晶。X射线衍射测试的单晶结构数据表明,该配合物属三斜晶系,空间群为P-1(2)。采用DSC/TG测试了二聚物和配体的热分解性能,发现配合物和配体的熔化和分解过程同时进行,且配体与Cu形成双核配合物后,热稳定性增高。

The reaction of CuCl2 ·2H2O with N-（ o-chloro benzoyl）-N＇-（2,3-dimethyl phenyl）-thiourea gave a new copper （I） complex. At the room temperature, the single crystal of the symmetric unit C32H30N4O2CuCl3S2·CH2Cl2 dimer was obtained by slowly evaporation solvent. The crystal structure was determined with X-ray diffractometer. Crystal data： trielinic, space group P-1 （2）. Furthermore, the thermal behavior of the title compound was studied. Thermodynamic properties proved that the melting and decomposition of the compound are overlapping. And the thermogravimetric analysis indicated that the thermostability of the ligand after forming the complexes has the very great degree enhancement.
