[(1,2,5,6-η)-Cyclo-octa-1,5-diene](4-isopropyl-1-methyl-1,2,4-triazol-5-yl-idene)(tri-cyclo-hexyl-phosphane-κ)iridium(I) tetra-fluorido-borate di-chloro-methane monosolvate.

The title compound, [Ir(CH)(CHN)(CHP)]BF·CHCl, a triazole-based N-heterocyclic carbene iridium(I) cationic complex with a tetra-fluorido-borate counter-anion, crystallizes with one di-chloro-methane solvent mol-ecule per formula unit. The Ir atom of the cationic complex has a distorted square-planar coordination environment, defined by a bidentate cyclo-octa-1,5-diene (COD) ligand, an N-heterocyclic carbene, and a tri-cyclo-hexyl-phosphane ligand. The complex crystallizes in a -centered monoclinic unit cell and has an unusually high number of eight formula units.
