Synthesis, characterization, and computational study of MoSF4.
Molybdenum sulfide tetrafluoride was synthesized from MoF(6) and S(Si(CH(3))(3))(2) in CFCl(3) at low temperature and was fully characterized by Raman, infrared, and (19)F NMR spectroscopy and by X-ray crystallography. The crystal structure revealed that MoSF(4) forms infinite fluorine-bridged chains. Quantum-chemical calculations using B3LYP and PBE1PBE methods were used to calculate the gas-phase geometry and vibrational frequencies of monomeric MoSF(4) and (MoSF(4))(3)F(-). The vibrational frequencies of (MoSF(4))(3)F(-) have been used in the assignment of the vibrational spectra of solid MoSF(4). Natural bond order analyses were carried out for monomeric MoSF(4) and, for comparison, for WSF(4).
