Synthesis and Characterisation of Organosilicon and Organotin Complexes derived from DHA Ligand

Abstract

Organosilicon(IV) and organotin(IV) complexes with dehydroacetic acid and amino ether Schiff base ligand have been described with the help of elemental analyses, electronic, infrared, multinuclear magnetic resonance spectroscopy. Analysis of data suggested that the Schiff base provides two bidentate NO domains and was coordinated to silicon and tin moiety through the imine nitrogen and hydroxyl oxygen atom forming penta coordinated and hexa coordinate complexes in 1: 2 and 1: 1 molar ratio. Thermal studies of the synthesized organotin compounds shows that they are stable and decomposition of the complexes occur in two steps with the formation of metal oxides as the end product.
