[ O -Isopropyl- N -(4-nitrophenyl)thiocarbamato- κS ]-(tri-4-tolylphosphine- κP )gold(I)

The synthesis, spectroscopic characterization and X-ray crystal structure of the title compound, (4-tolyl)₃PAu[SC(O-<i>i</i>-Pr)=NC₆H₄NO₂-4] (<b>1</b>) are described. Spectroscopy exhibited the expected features confirming the formation of the compound. The molecular structure of <b>1</b> confirms the expected linear P&#8315;Au&#8315;S coordination geometry defined by thiolate-S and phosphane-P atoms. The nearly 7&#176; deviation from linearity is ascribed to the close approach of the imine-bound phenyl group, indicative of a semi-localized Au^&#8230;<i>&#960;</i>(arene) interaction. The three-dimensional molecular packing is consolidated by methyl- and tolyl-C&#8315;H^&#8230;O(nitro) and tolyl-C&#8315;H^&#8230;<i>&#960;</i>(tolyl) interactions.
