The reaction of triphenyltin hydroxide with 2-furanyl, 2-furanvingl, 2-(5-terbutyl) furanyl, 2-(5-benzoyl) furanyl, 2-pyridinyl, 4-pyridinyl, 3-indolyl, 3-indolmethyl, 3-indolethyl and 3-indolpropyl carboxylates in 1:1 stoichiometry yields triphenyltin esters of heteroaromatic carboxylic acids Ph3SnO2CR. All compounds are characterized by elemental analysis, IR and H-1 NMR. The crystal structure of the triphenyltin ester of 4-pyridinyl carboxylic acid (6) is determined by single crystal X-ray diffraction. In compound (6), the tin atom is rendered five-coordinate in a trigonal bipyramidal structure by coordinating with the 4-pyridinyl carboxlate group. The resulting structure is a linear polymer containing Sn-O bond lengths of 0.2160(5)-0.2166(5) nm and Sn-N bond lengths of 0.2512(6)-0.2612(6) nm. (C) 2004 Elsevier Ltd. All rights reserved.

Abstract Six organotin(IV) complexes of type Me2SnL2, Bu2SnL2, and Ph3SnL [where L = indole-3-butyric acid (1, 2 and 3) or indole-3-propionic acid (4, 5 and 6)] have been synthesized by the reactions of the corresponding diorganotin(IV) oxide and triphenyltin(IV) hydroxide with respective indole-3-butyric acid (IBH) or indole-3-propionic acid (IPH) in the desired molar ratios of 1:2/1:1. All of the
