Organotin(IV) complexes of kojic acid and maltol of the type R3Sn(L) and R2Sn(L)Cl [R=C6H5CH2-, p-ClC6H4CH2-; HL=kojic acid, maltol] have been synthesized in anhydrous THF. They were characterized by UV, IR, 1H NMR, and mass spectral studies. Their activity vs. E. coli, S. aureus and P. pyocyanea bacterial strains have been studied and the general order of activity is S. auresu>P. pyocvanea>E. coli. In all the complexes, the ligand acts as bidentate, forming a five membered chelate ring. All the complexes are 1:1 metal ligand complexes. Various thermodynamic parameters have been calculated for the first two decomposition steps using TG/DTA/DSC curves, (p-ClC6H4CH2)3Sn(L) complexes have the minimum and (C6H5CH2)2Sn(L)Cl complexes have the maximum activation energy.
