A mononuclear manganese(Ⅱ) complex,trans-[MnL2(NCS)2] (L=3-(p-methoxyphenyl)-4-(p-chlorophenyl) -5-(2-pyridyl)-l,2,4-triazole),was synthesized and characterized by FTIR,ESI-MS,TG and X-ray crystallography.The complex crystallizes in monoclinic system with space group P21/c,a=1.458 5(3) nm,b=0.915 00(18) nm,c=1.6163(3) nm,β=101.70(3)°,V=2.1122(7) nm3,Z=2,and final R1=0.058 5.The manganese atom lies in a distorted octahedral environment with two NCS- 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 260 C.Magnetic data show that the complex is paramagnetic in the range of 1.8～300 K.CCDC:833359.
