Abstract

AbstractUsing single‐crystal to single‐crystal solid/gas reactivity the gold(I) acetylene complex [Au(L1)(η2‐HC≡CH)][BArF4] is cleanly synthesized by addition of acetylene gas to single crystals of [Au(L1)(CO)][BArF4] [L1=tris‐2‐(4,4′‐di‐tert‐butylbiphenyl)phosphine, ArF=3,5‐(CF3)2C6H3]. This simplest gold‐alkyne complex has been characterized by single crystal X‐ray diffraction, solution and solid‐state NMR spectroscopy and periodic DFT. Bonding of HC≡CH with [Au(L1)]+ comprises both σ‐donation and π‐backdonation with additional dispersion interactions within the cavity‐shaped phosphine.
