Abstract
Reactions of tantalum(V) isopropoxide with O,O'-dialkyldithiophosphoric acids in equimolar ratio yield tetraisopropoxy tantalum(V) dialkyl dithiophosphates, (PriO)4Ta[S2P(OR)2] (where R = Et, Prn, Pri, Bni, and C6H5) as hydrolysable, yellow viscous liquids, soluble in common organic solvents and monomeric in freezing benzene. These have been characterized by molecular weight determinations and spectral studies like IR and NMR (1H, 13C and 31P). Octahedral structures with chelating bidentate dithiophosphate moieties are suggested for these complexes.
