[(1,2,5,6-η)-Cyclo­octa-1,5-diene](1-ethyl-4-isopropyl-1,2,4-triazol-5-yl­idene)(tri­phenylphos­phane)iridium(I) tetra­fluorido­borate di­chloro­methane sesquisolvate

The synthesis and crystal structure of a new triazole-based N-heterocyclic carbene iridium(I) cationic complex with a tetra­fluorido­borate counter-anion and solvating di­chloro­methane, [Ir(C(8)H(12))(C(7)H(13)N(3))(C(18)H(15)P)]BF(4)·1.5CH(2)Cl(2), is reported. The Ir(I) center of the cationic complex has a distorted square-planar conformation, formed by a bidentate cyclo­octa-1,5-diene (COD) ligand, an N-heterocyclic carbene, and a triphenylphosphane ligand. There are weak hydrogen-bonding inter­actions between C—H groupings of the iridium complex and F atoms of the [BF(4)](−) counter-ions. The atoms of the COD ligand are disordered over two sets of sites in a 0.65:0.35 ratio and two of the F atoms of the anion are disordered over adjacent sites in a 0.6:0.4 ratio. One of the di­chloro­methane solvent mol­ecules is disordered about an inversion center with 0.5 occupancy. [Image: see text]
