Abstract
Effect of dimethyltin(IV) complexes of different substituted phenyl acrylic acids on the ability of Agrobacterium tumefaciens to cause tumours in plants was studied by using potato discs. The results demonstrated significant inhibition of tumours formation. All the compounds were synthesized and characterized by using analytical techniques, i.e. FTIR, multinuclear NMR (H-1, C-13, F-19 and Sn-119) and mass spectrometry. These studies explain that dimethyltin(IV) derivatives exist in a deformed octahedral environment known as skew trapezoidal geometry with four strong and two weaker bonds.
