摘要

本文报道了fNiL2(NCS)2(CH3OH)2](L=2.[[(4-吡啶)甲基]硫]-1H-苯并咪唑)配合物的合成,并通过IR、X-射线单晶衍射、热稳定性进行了表征.晶体结构测试表明:该配合物属于单斜晶系,空间群 P21,晶胞参数:α＝94420(12)nm,b=1.35733(17)am,c=1.341 64(17)nm,β=97.9830(10)°,V=1.7028(4)am3,Z=2,F(000)=748,D=1.407 g·cm-3,Final GooF=1.027,R1=0.0468,wR2=0.1071.中心Ni(Ⅱ)原子采用六配位,分别与2个2-I[(4-吡啶)甲基]硫]-1H-苯并咪唑上的2个N原子,2个硫氰酸根的2个N原子和2个甲醇分子上的2个0原子进行配位.在Ni(Ⅱ)基本配位单元之间存在N…H-O氢键,形成一维双链堆积结构.%A nickel(Ⅱ) complex [NiL2(NCS)2 (CH3OH)2] (L =2-[[(4-Pyridyl)methyl]thio]-1H-benzimidazole) was synthesized and characterized by IR spectra, X-ray diffraction and TG analysis. Crystal data for this complex:monoclinic, space group P21, a=0.944 20(12) nm, b=1.357 33(17) nm, c=1.341 64(17) nm, β=97.983 0(10)。, V=1.7028(4) nm3, Z=2, F(000)=748, Dc=1.407 g·cm-3, Final GooF=1.027, R1=0.0468, wR2=0.107 1. The crystal structure shows the nickel(Ⅱ) atom is six-coordinated with two nitrogen atoms from two 2-[[(4-Pyridyl)methyl]thio]1H-benzimidazole, the other two nitrogen atoms from two thiocyanate radical and two oxygen atoms from methanol molecules. The double-chain one dimensional motifs are formed by hydrogen bonds N…H-O conecting different nickel(Ⅱ) units. CCDC: 792992.
