%X Crystals of the title compound, Ph4As+ [MoO(SPh)4]-, belong to the triclinic space group P&#299; with cell dimensions a 12.623(8), b 14.295(7), c 14.301(9) &#506;, &#945; 94.43(4), &#946; 111.43(5), &#947; 65.70(4)&#176; and Z2. The structure has been refined with diffractometer data measured with Mo K&#945; radiation to give a conventional R factor of 0.056 for 3215 unique terms. The Mo, As, S and O atoms were refined with anisotropic temperature factors and the C atoms with isotropic factors. The square- pyrimidal [MoO(SPh)4]- anion has the Mo atom lying 0.82 &#506; from the basal plane of the four S atoms with Mo-O 1.699(9) &#506;, the mean Mo-S bond lengths 2.403(5) &#506; and the mean S...S distance 3.20(3) &#506;. The geometry about the As atom in the Ph4As+ cation is regular tetrahedral, the mean As-C bond length being 1.91(1) &#506;.
