Abstract:

Cy2NH2BzCO2•SnPh3Cl, Bz2NH2BzCO2•SnPh3Cl, BzCO2SnPh3•SnPh3Cl•1/4Bz2NH2Cl, Bz2NH2BzCO2•SnPhCl(OH)2, Bz2NH2BzCO2•SnBu2Cl2, [BzCO2SnPh3][SnPhCl3•EtOH•H2O] adducts and complexes have been obtained on allowing Cy2NH2BzCO2 or Bz2NH2BzCO2•4H2O to react respectively with SnPh3Cl, SnPh2Cl2 or SnBu2Cl2 in specific ratios. The molecular structures of these compounds have been determined on the basis of infrared and NMR data. The suggested structures are discrete, dimers and tetramer, the tin atom being tetra-, penta- and hexacoordinated; the benzyl carboxylate anions are monodentate, bidentate and chelating and the cations involved in hydrogen bonds.

Keywords:

bipyramidal trigonal environment, cations, chelating BzCO2- anion, hydrogen bonds, tin centre.
