| 中文摘要: |
| 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℃. |
