Di- and triphenyltin(IV) complexes of the compositions Ph2SnCln (XBHA)2-n and Ph3Sn(XBHA) (where n=O or 1, X=p-Cl or p-NO2 and BHA=anion of the hydroxamic acid, BH2A) have been synthesized by the reactions of Ph2SnCl2 or Ph3SnCl with the potassium salts of the respective p-chloro or p-nitrobenzohydroxamic acids in a MeOH/THF mixture. The complexes have been characterized by elemental analyses, molar conductance, molecular weight determinations and IR spectra. The results indicate that the ligand is bidentate, coordinating through the carbonyl and hydroxylamine oxygens. The reactions of Ph2SnCl(XBHA) with sodium derivatives of acetylacetone, dibenzoylmethane and salicylaldehyde (NaL) have led to the formation of mixed ligand complexes of the type Ph2Sn(XBHA). L Thermal decomposition of the complexes in an air stream yielded pure SnO2 at 700-800 °C.
