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 complex [Zn (OBimB) Cl2] .DMF.H2O (OBimB is 1,2-bis (2-benzimidazolyl) benzene) was synthesized and characterized by X-ray single crystal diffraction. The crystal belongs to the monoclinic space group P21 / c with unit cell parameters of a = 1.251 22 (9) nm, b = 1.039 80 (7) nm, c = 1.827 94 ) °, V = 2.367 2 (3) nm3, Z = 4, Dc = 1.509 g.cm-3. The final finishing results are: R1 = 0.043 0, wR2 = 0.093 9. In the complex structure, each Zn (Ⅱ) atom coordinated with two N atoms and two chloride ions from the V configuration OBimB ligand respectively to form a twisted tetrahedral structure. Photoluminescence testing of ligands and complexes shows that intramolecular fluorescence of the ligand belongs to the light emission.
