摘要

摘要制备了三乙基二氯铵[N-[(2-氧苯基)甲基]valinato]-苯基锡(iv)，并用光谱法和单晶x射线晶体学对其进行了表征。该化合物由三乙基铵阳离子和锡配合物作为阴离子组成。锡配合物由O,N,O-希夫碱配体与SnCl2Ph配位组成。锡原子呈畸变八面体配位几何。核磁共振波谱研究表明，罕见的六配位锡配合物是作为动力学控制产物形成的。固体产物储存数年导致转变为热力学稳定的五配位锡配合物。

Synthesis and crystal structure of an ionic phenyltin(iv) complex of N-salicylidene-valine

Abstract Triethylammonium dichloro[N-[(2-oxyphenyl)methylidene]valinato]-phenyl-tin(iv) was prepared and characterized by spectroscopic methods and single crystal X-ray crystallography. The compound consists of a triethylammonium cation and a tin complex as anion. The tin complex is composed of a tridentate O,N,O-Schiff base ligand coordinated to a SnCl2Ph unit. The tin atom is in distorted octahedral coordination geometry. NMR spectroscopic studies have shown that the unusual hexa-coordinated tin complex was formed as a kinetically controlled product. Storage of the solid product for several years led to a transformation into a thermodynamically stable penta-coordinated tin complex.
