Descripción
Sumario: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 (P2(1)/c) symmetry and a distorted tetra­hedral geometry around the nickel center, with the cyclo­octa­diene 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 cyclo­octa­diene (COD) ligand. One mol­ecule of tetra­hydro­furan (THF) is co-crystallized with the nickel complex and has positional disorder.
