%X The title compounds, R3PAuSC(= NPh )OR&#8242;, R = Et, Ph or Cy and R&#8242; = Me, Et, Pr, Pri or Cy, have been prepared and characterized by spectroscopic methods ( i.r., 1H and 13C n.m.r. and f.a.b . m.s .) and, in the case of the R = Ph and R&#8242; = Me compound, by single-crystal X-ray diffraction methods. The spectroscopic data are consistent with the R3PAu moiety being coordinated by the sulfur atom of the thiolate ligand. This has been confirmed by an X-ray study on Ph3PAuSC(= NPh )OMe which shows the gold atom to be linearly coordinated by the phosphorus and sulfur atoms; Au-P(1) 2.258(1), Au-S(1) 2.301(1) &#506; and P-Au-S 177.7(1)&#176;. Crystals of Ph3PAuSC(= NPh ) OMe are triclinic, space group p&#299;, with unit cell dimensions: a 10.825(1), b 12.553(2), c 8.914(2) &#506;, &#945; 97.86(2), &#946; 93.79(1), &#947; 88.60(1)&#176;, V 1197.1 &#506;3, Z 2. The structure was refined by a full-matrix least-squares procedure to R 0.028 for 4409 reflections with I &#8805; 2.5&#963;(I).
