5-氯-6-羟基吡啶甲酸三苯基锡酸酯的合成和晶体结构

Synthesis and Crystal Structure of Triphenyltin Ester of 5-Chloro-6-hydroxynicotinic Acid

由1:1的三苯基氢氧化锡和5-氯-6-羟基吡啶甲酸反应得到5-氯-6-羟基吡啶甲酸三苯基锡酸酯.在此化合物的结构中,锡原子与三个苯基碳原子和两个氧原子相结合,一个氧原子来自羧基,另一个来自酚羟基,呈五配位变形的三角双锥结构,酚羟基氧原子与其相邻的锡原子键合形成一维链状结构.

A novel organotin compound [Ph3Sn（OCOC5H2N-3-Cl-5-O-6）]. has been synthesized by the reaction of tripnenyltin hydroxide with pyridine-3-earboxylic acid in 1：1 ratio The molecular structure presents five-coordinated trigonal bipyramidal structure because the tin atom is combined with three phenyl carbon atoms and two oxygen atoms which are respectively from carboxylate and phenolic hydroxide. A one-dimensional linear polymer is formed by the interaction between the O atom of phenolic hydroxide and the adjacent tin atom.
