Single-Crystal to Single-Crystal Synthesis of a Gold(I)-Ammonia Complex and H/D Exchange In Crystallo with D2O

Abstract

Single-crystal to single-crystal solid/gas reactivity of [LAu(C2H4/CO)][BArF4] [L = tris-2-(4,4'-di-tert-butylbiphenyl)phosphine] with NH3 or 15NH3 gives the ammonia complexes [LAu(NH3/15NH3)][BArF4]. Solid-gas H/D exchange with D2O vapour gives the ND3 isotopologues, while reaction with HCl vapour affords [1-Cl]/[15NH4][BArF4], identifying a lattice encapsulated ammonium as a plausible intermediate species for H/D exchange with D2O by a proton rebound mechanism.
