Abstract
A new triazole-based N-heterocyclic carbene iridium(I) cationic complex with a tetra-fluorido-borate 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 cyclo-octa-1,5-diene (COD) ligand, an N-heterocyclic carbene, and a tri-phenyl-phosphane ligand. The crystal structure comprises C-H⋯π(ring) inter-actions that orient the phenyl rings; non-classical hydrogen-bonding inter-actions between the cationic complex and the tetra-fluorido-borate anion are also present. The complex crystallizes in a triclinic unit cell with two structural units and an incorporation of di-chloro-methane solvate mol-ecules with an occupancy of 0.8.
