The reactions of hexabutylditin with monofunctional bidentate Schiff bases in 1:2 molar ratio were studied in the medium of anhydrous benzene. Complexes of the type R₃Sn-SB (where R= -C₄H₉ and SB is Schiff base) have been synthesized. All reactions were not so facile and tin-tin bond was cleaved in preference to the tin-carbon bond. The resulting derivatives were obtained in the form of yellow liquids while some were found to be solids. They are soluble in common organic solvents and are highly sensitive to the atmospheric moisture. These complexes were found to be monomers. In these complexes, the tin atom probably attains coordination number of five and have trigonal bipyramidal structure.
