SYNTHES1S AND CHARACTER1ZATION OF SOME TIN (H) COMPLEXES

The reactions of Tin (II) chloride with a number of nitrogen and oxygen organic ligands in nona- queoussolventarereported. Complexeswere prepared with dimethyl-o-phenanthroline, tripyridyl dimethyl bipyridyl, pyrazine, hexamine, dimethyl hydrazine, benzotriazole, 3-picoline, methyi pyridine-l-oxide and alizarine-red-S. Adducts obtained from the reactions with diphenylphosp- hino methane, diphenylphosphino ethane and triphenyl phosphine indicate thatthe ligands were oxidized, and coordination occured through the oxygen atom. No products were obtained on using xanthone and xanthene as ligands and the compounds AV ere recovered unchanged. St~ ructural aspects of the compounds are discussed
