[(1,2,5,6-η)-Cycloocta-1,5-diene](4-isopropyl-1-methyl-1,2,4-triazol-5-ylidene)(triphenylphosphane)iridium(I) tetrafluoridoborate dichloromethane 0.8-solvate

摘要
A new triazole-based N-heterocyclic carbene iridium(I) cationic complex with a tetrafluoridoborate counter-anion, [Ir(C8H12)(C18H15P)(C6H11N3)]BF4·0.8CH2Cl2, has been synthesized and structurally characterized. The central IrI atom of the cationic complex has a distorted square-planar coordination environment, formed by a bidentate cycloocta-1,5-diene (COD) ligand, an N-heterocyclic carbene, and a triphenylphosphane ligand. The crystal structure comprises C—H⋯π(ring) interactions that orient the phenyl rings; non-classical hydrogen-bonding interactions between the cationic complex and the tetrafluoridoborate anion are also present. The complex crystallizes in a triclinic unit cell with two structural units and an incorporation of dichloromethane solvate molecules with an occupancy of 0.8.Unlabelled Image
