The crystal structure of the title compound, [Ni(C 25 H 28 N 4 )(C 8 H 12 )]·C 4 H 8 O or ( Mes NHC 2 Me)Ni(COD), which contains a bidentate N-heterocyclic carbene (NHC) ligand with mesityl aryl groups is reported. The complex at 100 K has monoclinic ( P 2 1 / c ) symmetry and a distorted tetra-hedral geometry around the nickel center, with the cyclo-octa-diene ligand coordinated in a κ 2 ,η 2 fashion. The bidentate NHC ligand is not planar, with a C(carbene)-Ni-C(carbene) angle of 91.51 (12)°, resulting in the mesityl groups being on the same side of the cyclo-octa-diene (COD) ligand. One mol-ecule of tetra-hydro-furan (THF) is co-crystallized with the nickel complex and has positional disorder. |
