Synthetic and applied aspects of tin(IV) and organotin(IV) complexes of various Schiff bases

Synthetic Inorganic and Metallo-organic Research Laboratory, Department of Chemistry, University of Allahabad, Allahabad-211 002, Uttar Pradesh, India E-mail : rajalkoxy@yahoo.com Manuscript received online 14 October 2014, accepted 22 October 2014 The tin(IV) and organotin(IV) moiety form complexes with Schiff bases containing oxygen, nitrogen, sulphur or phosphorus coordinating atoms with varied coordination number. The development of new spectroscopic techniques FT-IR, multinuclear (1H-, 13C-, 119Sn-) NMR, X-ray crystallography provided useful information about the structure. Recently, organotin(IV) complexes of Schiff base has extensively studied due to their antimicrobial, antinematicidal, antiinflammatory, antitumour and antiurease activities. We reviewed the literature of tin(IV) and organotin(IV) complexes taking in to accounts on synthesis, spectroscopic characterization, biological importance as well as toxic behaviour of tin(IV) complexes of Schiff bases reported during recent years
