title: 1,3-Dimesitylimidazolidinium tetra-chloridogold(III) dichloro-methane solvate.
abstract: The title ionic compound, (C(21)H(27)N(2))[AuCl(4)]·CH(2)Cl(2), was obtained from the reaction of 1,3-dimesitylimidazolidinium chloride with t-BuOK and a solution of AuCl(3) in tetra-hydro-furan. In the crystal structure, numerous weak C-H⋯Cl hydrogen bonds form double layers parallel to (100), which are further stabilized by π-π inter-actions between mesitylene rings [centroid-centroid distance = 4.308 (4) Å], resulting in the formation of a three-dimensional supra-molecular assembly.
