Synthesis, spectral characterization and bio-analysis of some organotin(IV) complexes

Five novel organotin(IV) derivatives have been synthesized by refluxing trimethyl, triethyl, tributyl, and triphenyl and tribenzyltin chloride with Schiff base derived from salicylaldehyde and adenine. These compounds were characterized by spectroscopic (IR, H-1, C-13, Sn-119-NMR, Sn-119 Mossbauer) techniques and elemental analysis. Based on these results, trigonal bipyramidal geometry is suggested. The synthesized compounds were also treated with various microorganisms and found to be active. (C) 2008 Elsevier Masson SAS.
