| 摘要: 以3-对溴苯基-4-对甲苯基-5-(2-吡啶基)-1，2，4-三氮唑(L)作为配体，合成了1个铜配合物trans-[CuL2(ClO4)2]，对其进行了红外、电喷雾质谱、热重分析和单晶结构表征，该配合物属于三斜晶系，空间群P1，a=0.829 29(15) nm，b=0.854 48(16) nm，c=1.502 7(3) nm，α=83.517(2)°，β=89.200(2)°，γ=73.064(2)°，V=1.011 9(3) nm3，Z=1，R1=0.041 2。单晶结构表明，铜离子处于1个扭曲的八面体配位环境中，2个高氯酸根离子呈反式配位，每个配体L通过三氮唑上的1个氮原子和吡啶氮原子参与配位。热重分析表明该配合物在310 ℃开始发生分解。 | |

| Abstract: A copper(Ⅱ) complex, trans-[CuL2(ClO4)2], (L=3-(p-bromophenyl)-4-(p-methylphenyl)-5-(2-pyridyl)-1,2,4-triazole), was synthesized and characterized by FTIR, ESI-MS, TGA/DSC and X-ray crystallography. The complex crystallizes in triclinic system with space group P1, a=0.829 29(15) nm, b=0.854 48(16) nm, c=1.502 7(3) nm, α=83.517(2)°, β=89.200(2)°, γ=73.064(2)°, V=1.011 9(3) nm3, Z=1 and final R0.041 2. The copper atom lies in a distorted octahedral environment with two ClO4- ions in the trans positions. The ligand L coordinates via one triazole nitrogen and one pyridine nitrogen atom. The TG analysis shows that the complex is stable below 310 ℃. CCDC: 843042. | |
