Some new bimetallic carboxylates of tin and germanium with general formula [C2H5](2)Sn[O2CCH2CH(R-2)GeR31] where R-1 = m-CH3C6H4, p-CH3C6H4, C6H5, R-2 = o-CH3C6H4, p-CH3C6H4, o-CH3OC6H4, C6H5, CH3, have been prepared by the condensation reaction of diethyltin oxide and triarygermyl(substituted)propanoic acid in 1:2 mole ratio, respectively, and characterized by multinuclear (H-1, C-13, Sn-119) NMR, Sn-119m Mossbauer and IR spectroscopy. The X-ray crystal structure of the ligand I-4[(C6H5)(3)GeCH(o-CH3OC6H4)CH2COOH] delineate four coordinated germanium atom with a peculiarity of having a molecule of solvent (CHCl3)The chiral center in the synthesized compounds was identified on the basis of H-1 NMR data and measurements of angle of rotations.
