Abstract: | The title salt, methyl (1R,2R,3S,5S,8S)‐3‐benzoyloxy‐8‐methyl‐8‐azabicyclo[3.2.1]octane‐2‐carboxylate tetrachloroaurate(III), (C17H22NO4)[AuCl4], has its protonated N atom intramolecularly hydrogen bonded to the O atom of the methoxycarbonyl group [N⋯O = 2.755 (6) Å and N—H⋯O = 136°]. Two close intermolecular C—H⋯O contacts exist, as well as five C—H⋯Cl close contacts. The [AuCl4]− anion was found to be distorted square planar. |
