Tetraphenylantimony(V) O,O″-dialkyl dithiophosphates [Sb(C 6H5)4{S2P(OR)2}] (R = s-C4H9, c-C6H11) : synthesis, structures, and 13C and 31P CP/MAS NMR spectra

• Tetraphenylantimony(V) O,O′-di-sec-butyl dithiophosphate (I) and tetraphenylantimony(V) O,O′-dicyclohexyl dithiophosphate (II) [Sb(C 6H5)4{S2P(OR)2}] (R = sec-C4H9 or cyclo-C6H11) were obtained. Their structures and spectroscopic properties were studied by X-ray diffraction analysis and 13C and 31P CP/MAS NMR spectroscopy. The dithiophosphate (Dtph) ligands in complexes I and II were found to be coordinated in S-monodentate and S,S′-bidentate fashions, respectively (MAS NMR data). According to X-ray diffraction data, the coordination polyhedron of antimony in molecular structure I is a trigonal bipyramid with unusual monodentate coordination of the Dtph group in the axial position.
