A series of diorganotin dicarboxylates of the general formula (CH3)2Sn(OCOCHR3CHR2GeR1)2 where R1=(C6H5)3 , (P-CH3C6H4)3 , N(CH2CH2O)3 , R2=C6H5 , H, CH3 , P-CH3OC6H4 , P-ClC6H4 , P-CH3C6H4 , R3=CH3 and H, have been synthesized by the reaction of dimethyltin oxide with germanium substituted propionic acid in 1:2 molar ratio in toluene. The H2O formed was removed azeotropically using a Dean and Stark apparatus. All the compounds have been characterized by IR, multinuclear (H1 , C13 , S119n ) NMR, mass and Mössbauer spectroscopies. All compounds were found to have potential activity against bacteria.
