二丁基锡邻香草醛-2-噻吩甲酰腙的合成及晶体结构(英文)

Synthesis and Characterization of Dibutyltin (Ⅳ) o-vanillin-2-thiophenoylhy Drazone

利用二丁基二氯化锡与邻香草醛-2-噻吩甲酰腙反应,合成了新的二有机锡希富碱衍生物[(n-C4H_9)_2Sn[(C_(13)H_(10)N_2O_3S)]_2,并用元素分析、红外光谱、核磁共振氢谱和X-射线单晶衍射对该化合物进行了表征.测试结果表明,在配合物中锡原子为五配位的三角双锥配位环境.同时,化合物分子间通过Sn…O弱作用形成弱桥联二聚体.

A new dibutyltin （Ⅳ） complex with Schiff base of o-vanillin-2-thiophenoylhydrazone [（n-C4Hg）2Sn [（C13 H10 N203S）-]2 was synthesized by the reaction of （C4Hg）2SnCl2 with o-vanillin-2- thiophenoylhydrazone. Complex has been characterized by elemental, IR,^1H NMR analyses and X-ray crystallographic diffraction analyses. The tin atom exhibits a distorted trigonal bipyramid coordination geometry. Two molecules form a weak-bridged dimmer with weak interactions of Sn…O.
