Abstract

This paper describes the preparation and description of four new complexes [Bu2Sn(AA)Cl] (AA = glycine, DL-valine and L-leucine) and [Bu2SnPhen2] (Phen = DL-phenylalanine) They were characterized by elemental analyses of carbon, hydrogen, nitrogen, chlorine and tin; and by infrared, 119mSn-Mössbauer and 119mSn-RMN spectroscopies, and by the applications of TG and DSC techniques in dynamic helium atmosphere. For the [Bu2Sn(AA)Cl], trigonal bipyramidal tin species, AA were coordinated bidentatedly by the carboxylic oxygen and by the NH2 group. The [Bu2SnPhen2)], with tin atoms in trans-octahedral sites, had the Phen-coordinated by both carboxylic oxygen atoms.
