Synthesis and characterization of some new coordination compounds of organo
tin(IV) with nitrogen and oxygen donor ligands have been described. These h
ave been obtained by the reactions of dibutyltinoxide with monobasic bident
ate ligands derived by the condensation of 1-acetylfuran or 2-acetylthiophe
ne with glycine, beta-alanine, valine, leucine and tryptophan in 1:2 stoich
iometry. Suitable structures based on IR, multinuclear magnetic resonance (
H-1, C-13 and Sn-119) spectral studies have been indicated for these new de
rivatives.
