基于3-甲基-4-对溴苯基-5-(2-吡啶基)-1,2,4-三氮唑的锰配合物的合成和晶体结构

摘要

A new manganese(Ⅱ) complex, cis-[MnL2(NCS)2], (L=3-methyl-4-(p-bromophenyl)-5-(2-pyridyl)-1,2,4-triazole), was synthesized and characterized by X-ray crystallography, FTIR and ESI-MS spectra. The complex crystallizes in monoclinic system with space group P21, α=1.6480(2), b=0.90707(13), c=2.191 9(3)nm, β=97.454(2)°, V=3.248 8(8)nm3, Z=4 with final R=0.043 9. The manganese atom lies in a distorted octahedral environment with two NCS- ions in the cis positions. The ligand L coordinates via one triazole nitrogen and one pyridine nitrogen atom.%以3-甲基-4-对溴苯基-5-(2-比啶基)-1,2,4-三氮唑作为配体(L),合成了1个新的锰配合物[MnL2(NCS)2],对其进行了红外、电喷雾质谱和单晶结构表征,该配合物属于单斜晶系,空间群P21,α=1.6480(2)nm,b=0.90707(13)nm,c=2.191 9(3)nm,β=97.454(2)°,V=3.2488(8)nm3,Z=4,R1=0.0439.单晶结构表明,锰离子处于1个扭曲的八面体配位环境中,2个硫氰根离子呈顺式配位,每个配体L通过三氮唑上1个氮原子和吡啶上1个氮原子参与配位.
