The tri-n-butyltin(IV) complexes of 2-[(E)-2-(3-formyl-4-hydroxyphenyl)-1- diazenyl]benzoic acid and 4-[((E)-1-\2-hydroxy-5-[(E)-2-(2-carboxyphenyl)-1- diazenyl]phenyl\methylidene)amino]aryls (aryls = 4-CH3, 4-Br, 4-Cl, 4-OCH3) have been synthesized and characterized by 1H, 13C, 119Sn NMR, IR and 119mSn Mössbauer spectroscopic techniques in combination with elemental analysis. The crystal structures of two compounds, (Bu3Sn[O2CC6H 4\NN(C6H3-4-OH-5-CHO)\-o])n and (Bu3Sn[O2CC6H4\NN(C 6H3-4-OH(C(H)NC6H4Cl-4))\-o]) n, are reported.The crystallographic and 119Sn Mössbauer data both indicate that the tributyltin complexes form single-stranded polymeric structures in which the carboxylate O atoms of each aryl ligand bridge two Sn atoms. The Sn atoms have a slighly distorted trigonal bipyramidal coordination geometry with equatorial butyl groups and carboxylate O atoms occupying axial positions. The 119Sn NMR spectroscopic data and the 1J(13C-119/117Sn) coupling constant indicate a tetrahedral coordination geometry in non-coordinating solvents. The results of a toxicity study of a tributyltin compound on the second larval instar of Aedes aegypti mosquito larvae are reported. © 2004 Elsevier B.V. All rights reserved.
