一个双核锌配合物(ZnCl2)(PyBIm)2的合成及结构

摘要

A new binuclear zinc complex[(ZnCl2)(PyBIm)]2(PyBIm=2-(4-pyridyl)bemimidazole)has been synthesized by hydrothermal reaction.The complex crystallizes in triclinic P21 space group with crystal cell parameters of a=0.774 51(4)nm,b=1.252 49(5)nm,c=1.315 96(7)am,β=100.294(3)°,V=I.2560(1)nm3 and Z=2.The crystal X-ray analysis shows that Zn atom is coordinated by two C1 atoms and two N atoms from two PyBIm ligands in a interactions also exist in the structure.CCDC:800921.%在水热条件下,合成了1个新的双核锌配合物[(ZnCl2)(PyBIm)]2(PyBIm=2-(4-pyridyl)benzimidazole).该配合物为单斜晶系,P21空间群,晶胞参数a=0.77451(4)nm,b=1.25249(5)nm.c=1.31596(7)nm,β=100.294(3)°,V=I.2560(1)nm3,Z=2.结构分析表明,Zn被2个Cl原子和来自PyBIm配体的2个N原子配位,形成了1个变形四面体结构.在该配合物中,Zn…Zn距离为0.7094(5)am,结构中存在π…π堆积和氢键作用.
