Synthesis, spectroscopic characterization, and in vitro fungicidal activity of some organotin(IV) complexes

Triphenyl-and tribenzyltin(IV) complexes of the ligand (sodium 5,5-diethyl barbital) have been synthesized and characterized by various spectroscopic methods. Trigonal bipyramidal geometry is assigned to all the complexes on the basis of results obtained by 1 H, 13 C, and 119 Sn NMR spectroscopy, IR...

Summary:Triphenyl-and tribenzyltin(IV) complexes of the ligand (sodium 5,5-diethyl barbital) have been synthesized and characterized by various spectroscopic methods. Trigonal bipyramidal geometry is assigned to all the complexes on the basis of results obtained by 1 H, 13 C, and 119 Sn NMR spectroscopy, IR, and 119 mSn Mössbauer studies. Fungicidal activity of the complexes was studied using various plant pathogens via the hanging drop method. The triphenyltin(IV) complex of this ligand exhibited promising activity against all the plant pathogens at all concentrations used, while the tribenzyltin(IV) complex also showed significant fungicidal activity.
