摘要

Reactions of (R_3Sn)_2O (R=Ph, 2-ClC_6H_4CH_2, 2-FC_6H_4CH_2, 4-CNC_6H_4CH_2) with 5-chloro-6-hydroxynicotinic acid in 1/2 stoichiometry yielded eight triorganotin compounds. These compounds have been characterized by elemental analysis, IR and NMR spectroscopy. The crystal structures of triphenyltin esters of 5-chloro-6-hydroxynicotinic acid were determined by single crystal X-ray diffraction. In the compound, the tin atoms are rendered five-coordinated in a trigonal bipyramidal structure by coordinating though the three phenyl carbon atoms and two oxygen atoms one from carboxylate and other from the phenolic hydroxide. The resulting structure is one-dimensional linear polymers through an interaction between the O atoms of phenolic hydroxide and tin atoms of an adjacent molecule.
