氯化锌在特定的条件下分别和3,5-二甲基吡啶、3-乙基吡啶、3-乙酰吡啶配合生成新的锌配合物[ZnCl2(lut)2](1),[ZnCl2(etpy)2](2)and[ZnCl2(acpy)2](3),并用红外光谱、紫外可见光谱、元素分析、X-射线单晶衍射对这3种配合物分别进行了表征.结果表明,这3种配合物中锌以四配位的方式分别与来自2个吡啶配体中的氮和来自氯化锌中的2个氯联结,组成了1个扭曲的四面体构型.这3种配合物均具有比较弱的热稳定性和较好的非线性光学性质.
Under certain conditions, zinc chloride complexes with 3,5-dimethylpyridine, 3-ethylpyridine and 3-acetylpyridine to form a new zinc complex [ZnCl2 (lut) 2] etpy) 2] (2) and [ZnCl2 (acpy) 2] (3) were synthesized and characterized by IR, UV-Vis, elemental analysis and X-ray single crystal diffraction, respectively. The three complexes of zinc in a four-coordinated manner with nitrogen from two pyridine ligands and two chlorine from zinc chloride, forming a twisted tetrahedral configuration. These three The complexes have weaker thermal stability and better nonlinear optical properties.
