Single-crystal to single-crystal synthesis of a gold( <scp>i</scp> )-ammonia complex and H/D exchange <i>in crystallo</i> with D <sub>2</sub> O
Single-crystal to single-crystal solid/gas reactivity of [LAu(C<sub>2</sub>H<sub>4</sub>/CO)][BAr<sup>F</sup><sub>4</sub>] [L = tris-2-(4,4'-di-<i>tert</i>-butylbiphenyl)phosphine] with NH<sub>3</sub> or <sup>15</sup>NH<sub>3</sub> gives the ammonia complexes [LAu(NH<sub>3</sub>/<sup>15</sup>NH<sub>3</sub>)][BAr<sup>F</sup><sub>4</sub>]. Solid-gas H/D exchange with D<sub>2</sub>O vapour gives the ND<sub>3</sub> 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 D<sub>2</sub>O by a proton rebound mechanism.
