摘要
合成了(1,5-环辛二烯)氯铑二聚体([Rh(cod)Cl]2),用元素分析、红外吸收光谱、X射线单晶衍射仪(XRD)对其结构进行了表征,并用热重-差热(TG-TDA)分析测试其热分解特性。结果表明,该化合物为单斜晶系,P21/n空间群,晶胞参数为:a=0.72848(4)nm,b=2.51434(14)nm,c=0.88794(5)nm,β=91.0450(10)°,V=1.62612(16)nm3,R1=0.0235,wR2=0.0580,为一种同核双金属氯桥连化合物。TG-DTA测试显示该化合物分解峰出现在225℃。
A Rhodium(I)complex,[Rh(cod)Cl]2,was synthesized and characterized by the elemental analysis,infrared absorption spectroscopy and single crystal X-ray diffractometer,accurately determine its structure,and its thermal decomposition characteristics were characterized by TG-TDA.Its crystal belongs to monoclinic space group P21/n,and its unit cell parameters are a=0.72848(4)nm,b=2.51434(14)nm,c=0.88794(5)nm,β=91.0450(10)°,V=1.62612(16)nm3,R1=0.0235,wR2=0.0580.Its molecular structure is that two Rh(I)with two Cl-and two 1,5-cyclooctadiene(cod)ligands form a dinuclear chloride bridge compound.TG-TDA results showed that the peak decomposition temperature was 225℃.
