Abstract

Using single-crystal to single-crystal solid/gas reactivity the gold(I) acetylene complex [Au(L1)(η²-HC≡CH)][BAr^F₄] is cleanly synthesized by addition of acetylene gas to single crystals of [Au(L1)(CO)][BAr^F₄] [L1=tris-2-(4,4′-di-tert-butylbiphenyl)phosphine, Ar^F=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.
