ABSTRACT:
Monochloro-niobium(V) bis-O-alkyl/O-aryl trithiophosphates, ClNb[ROP(S)SS]2 (where R = Me, Et, Pri, Bui, Ph, CH3-Ph) have been synthesized by the reaction of niobium pentachloride with O-alkyl /O-aryl trithiophosphoric acid in 1:2 molar ratio, in refluxing ethanol. O-alkyl/O-aryl trithiophosphate derivatives of niobium (V) are pale yellow monomeric solids, soluble in co-ordinating solvents like DMSO, DMF and exhibit high sensitivity towards moisture. The newly synthesized derivatives have been characterized by elemental analysis, molecular weight measurement and spectroscopic (IR, 1H and 31P NMR) studies. On the basis of it is postulated that niobium is in penta-co-ordinated state and new derivatives show trigonal bipyramidal geometry. Two O-alkyl /O-aryl trithiophosphoric acid ligands are co-ordinated to niobium ion as a bidentate ligand chelating via two thiolate S atoms. Each of them forms a four-membered chelate ring.
