摘　　要：以苯并咪唑、溴化苄为配合物中配体(Bn-NHC)的原料,利用水热合成法制备了一种新型零维Zn配合物Zn(Bn-NHC)_(2)Br_(2).通过X-射线单晶衍射、元素分析、红外光谱、荧光分析等对目标配合物进行了结构表征及性质研究.结构分析表明:目标配合物属于三斜晶系,P 1空间群,晶胞参数a=1.0430 nm,b=1.0659 nm,c=1.3607 nm,α=109.361(11)°,β=90.269(12)°,γ=110.450(3)°,V=1.32476 nm^(3),Z=12.氮杂环卡宾配体上2个氮原子配位1个Zn离子形成零维结构.荧光测试表明配合物的荧光可归属于配体向金属的电荷转移.A new zero dimensional Zn complex Zn(Bn-NHC)_(2)Br_(2)was prepared by hydrothermal synthesis with benzimidazole and benzyl bromide as the raw materials of ligands(Bn-NHC)in the complex.The structures and properties of the target complexes were characterized by X-ray single crystal diffraction,elemental analysis,infrared spectrum and fluorescence analysis.Structural analysis showed that the target complex belonged to triclinic system with space group P 1,cell parameter a=1.0430 nm,b=1.0659 nm,c=1.3607 nm,α=109.361(11)°,β=90.269(12)°,γ=110.450(3)°,V=1.32476 nm^(3),Z=12.Two nitrogen atoms of the nitrogen heterocyclic carbene ligands coordinate with a zinc ion to form a zero-dimensional structure.Fluorescence measurements show that the fluorescence of the complexes can be attributed to the charge transfer from ligands to metals.
