title: {μ-5-[1,3-Bis(2,4,6-trimethyl-phen-yl)-3H-imidazolium-2-yl]-2-(2-oxoethenyl-1κC)furan-3-yl-2κC}-μ-hydrido-bis(tetra-carbonyl-rhenium) tetra-hydro-furan 0.67-solvate.
abstract: The title complex, [Re(2)(C(27)H(25)N(2)O(2))H(CO)(8)]·0.67C(4)H(8)O, was formed as a product in the reaction of a rhenium(I)-Fischer carbene complex with a free NHC carbene. The coordination environment about the two Re atoms is slightly distorted octahedral, including a bridging H atom. The imidazolium and furan groups are almost coplanar, whereas the mesityl substituents show an almost perpendicular arrangement with respect to both heterocyclic units. Mol-ecules of the complex pack in such a way as to form channels parallel with the bc unit-cell face diagonal running through the unit face diagonal. These channels are partially occupied by tetra-hydro-furan solvent mol-ecules.
