The novel triphenyltin (IV) esters of flufenamic acid (1), Hflu,[Ph3Sn (flu)](2), and of [2-(2, 3- dichlorophenylamino) benzoic acid](3), Hdcpa,[Ph3Sn (dcpa)](4) have been structurally characterized by means of vibrational and 1H, 13C NMR spectroscopic studies. The crystal and molecular structures of [SnPh3 (dcpa)(DMSO)] 4a are described. The molecular structure of 4a reveals that the Sn atom has a distorted trigonal bipyramidal coordination ...
