1,3-Bis(2,4,6-trimethylphenyl)-3H-imidazol-1-ium tetraoxidorhenate(VII)
Abstract
The title compound, (C21H25N2)[ReO4], 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.
