以3-对甲氧苯基-4-对氯苯基-5-(2-吡啶基)-1,2,4-三氮唑(L)为配体,合成了1个单核锰配合物trans-[MnL2(NCS)2],对其进行了红外、电喷雾质谱、热重和单晶结构表征,该配合物属于单斜晶系,空间群为P21/c,a=1.458 5(3)nm,b=0.915 00(18)nm,c=1.616 3(3)nm,β=101.70(3)°,V=2.112 2(7)nm3,Z=2,R1=0.058 5。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个硫氰根离子呈反式配位,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。热重分析表明该配合物在260℃开始发生分解。变温磁化率显示该配合物为顺磁性(1.8~300 K)。
One mononuclear manganese complex was synthesized with 3-p-methoxyphenyl-4-p-chlorophenyl-5- (2-pyridyl) -1,2,4-triazole (L) The complex belongs to the monoclinic system with the space group of P21 / c, a = 1.458 5 (3), and the complex of trans- [MnL2 (NCS) 2] was characterized by IR, ESI- ) nm, b = 0.91500 (18) nm, c = 1.6163 (3) nm, β = 101.70 (3) °, V = 2.112 2 (7) nm3, Z = 2 and R1 = 0.058 5. The single crystal structure shows that the manganese ions are in a twisted octahedral coordination environment and the two thiocyanate ions are trans coordinated. Each ligand L passes through one nitrogen atom on the triazole and one on the pyridine Nitrogen atoms participate in coordination. Thermogravimetric analysis showed that the complex began to decompose at 260 ℃. The temperature-dependent magnetic susceptibility shows that the complex is paramagnetic (1.8-300 K).
