title: 1,3-Bis(2,4,6-trimethyl-phen-yl)-3H-imidazol-1-ium tetra-oxidorhenate(VII).
abstract: The title compound, (C(21)H(25)N(2))[ReO(4)], was formed as the unexpected product in an attempted synthesis of a rhenium(I)-N-heterocyclic carbene (NHC) complex. The compound has crystallographic mirror symmetry with both the cation and the tetrahedral anion located across a mirror plane. The cation and anion are linked by a C-H⋯O hydrogen bond.
