合成了一个配合物[Zn(OBimB)Cl2]·DMF· H2O(OBimB为1,2-双(2-苯并咪唑基)苯),并用X射线单晶衍射仪测定了其晶体结构.晶体属单斜晶系,P21/c空间群,晶胞参数为:a=1.251 22(9) nm,b=1.039 80(7) nm,c=1.827 94(11) nm,β=95.508(2)°,V＝2.367 2(3) nm3,Z=4,Dc=1.509 g·cm-3.最后精修结果为:R1=0.043 0,wR2=0.093 9.在配合物结构中每个Zn(Ⅱ)原子分别与2个来自V构型OBimB配体的N原子、2个氯离子进行配位,形成了1个扭曲的四面体结构.配体和配合物的光致发光测试显示光发射属于配体的分子内荧光.

A complexe [Zn(OBimB)Cl2]·DMF·H2O based on a rigid bis(benzimidazoles) ligand OBimB (OBimB=1,2-bis(2-benzimidazolyl)benzene) has been synthesized and structurally characterized by X-ray single crystal diffractometry.The complex crystallizes in monoclinic system,P21/c space group with the cell parameters of a=1.251 22(9) nm,b=1.039 80(7) nm,c=1.827 94(11) nm,β=95.508(2)°,V=2.367 2(3) nm3,Z=4,and Dc=1.509 g· cm-3,the final R1=0.043 0,wR2＝0.093 9.In the structure of the complex the Zn atom is coordinated by two N atoms from a twisted V-shape conformational OBimB ligand and two Cl-anions in a distorted tetrahedral geometry.The photoluminescence measurements of the ligand and the complex show that the emissions are assigned to the intraligand fluorescence.CCDC:861572.
