Hydrogen bonding of the form N\u2014H...Cl<jats:sup>\u2212<\/jats:sup>...H\u2014N leads to inversion-symmetric dimers, which are further connected by C\u2014H...Au contacts.

The asymmetric unit contains two formula units, in each of which the chloride anion accepts a hydrogen bond from the cation and from the neutral molecule, and the two Au atoms are linked <jats:italic>via<\/jats:italic> an aurophilic interaction. A further hydrogen bond leads to inversion-symmetric dimers.
