Abstract The preparation and spectroscopic characterization of some complexes of the type Bu 2 Sn(LH) 2 ( LH = 5‐[( E )‐2‐(aryl)‐1‐diazenyl]‐2‐hydroxybenzoate) are reported. On the basis of spectroscopic evidence ( 1 H, 13 C, 119 Sn NMR, IR and 119m Sn Mössbauer) the compounds were judged to adopt the usual dicarboxylato structural type with a skew trapezoidal arrangement. This was further confirmed by X‐ray crystallography in the case of Bu 2 Sn(L 5 H) 2 (L 5 H = 5‐[( E )‐2‐(4‐chlorophenyl)‐1‐diazenyl]‐2‐hydroxybenzoate). Toxicity studies of the di‐ and tri‐organotin compounds on the second larval instar of Aedes aegypti mosquito larvae are reported. Copyright © 2003 John Wiley & Sons, Ltd.
