摘要: 采用不同的方法合成了3种酰腙的锌配合物[Zn(Lss)(phen)(DMF)](1)、{[Zn(HLdis)]2·2CH3OH}n2)和[Zn(Baf)2]·CH3OH(3),通过元素分析、红外光谱、紫外光谱和热重分析进行了表征,并经X射线单晶衍射分析它们晶体结构。13的晶体属于三斜晶系P1空间群,Zn(Ⅱ)的配位数为6;2属于单斜晶系P21/n空间群,Zn(Ⅱ)的配位数为5。3的前驱体是一种吡唑啉类化合物(C15H14N2O3,Pzl),它的晶体属于单斜晶系P21/c空间群;Pzl与锌离子配位时发生分子重排,开环产物HBaf以酰腙结构与Zn(Ⅱ)配位形成3。

Abstract: Three zinc complexes, namely[Zn(Lss)(phen)(DMF)] (1), {[Zn(HLdis)]2·2CH3OH}n (2) and[Zn(Baf)2]·CH3OH (3), formed from different acylhydrazone-type Schiff base ligands were synthesized by using different methods, and the compounds were characterized by IR, UV-Vis spectra and TGA. The X-ray diffraction analyses reveal that 1 and 3 crystallize in the triclinic space group P1 while 2 in monoclinic system space group P21/n. In 1 and 3, coordination number of the Zn(Ⅱ) is six, and the centric atom locate in a distorted octahedron geometry, while in 2 Zn(Ⅱ) is five-coordination in a distorted square-pyramidal geometry. The precursor of 3 is pyrazoline derivative with the formula C15H14N2O3 (Pzl) crystallizing in monoclinic system space group P21/c. Due to the coordination of Zn(Ⅱ) causing the intramolecular rearrangement of Pzl, the ring open product HBaf in the form of an acylhydrazone structure coordinates with Zn(Ⅱ) to form complex 3.
