Violet crystals of AsPh4[W(O)Cl3(HN3S2)] were obtained by partial hydrolysis of AsPh4[WCl4(N3S2)] in a saturated solution in CH2Cl2/CCl4. Its IR spectrum is reported. The crystal structure was determined by X-ray diffraction (2284 independent observed reflexions, R = 0.041). Crystal data: triclinic, space group P1̄, Z = 2, a = 812.2, b = 1268.4, c = 1343.9 pm, α = 88.58, β = 82.04 and γ = 88.26°. The compound consists of AsPh4 cations and [W(O)Cl3(HN3S2) anions in which the tungsten atoms have a distorted octahedral coordination with one oxo-ligand (171 pm), three chlorine atoms and two nitrogen atoms of the planar (HN3S7)2⊖ ligand. The WN bond lengths are 183 and 226 pm; the longer WN bond is due to the hydrogen atom attached to its N atom and to the trans influence of the oxo group. The crystal packing corresponds to one of the types frequently found among tetraphenylphosphonium compounds with cations stacked to parallel columns.

Keywords: Oxo-trichloro-hydrocyclothiazeno-tungstate(VI); Synthesis; IR Spectrum; Crystal Structure
