Abstract
A new triazole-based N-heterocyclic carbene iridium(I) cationic complex with a tetra-fluorido-borate counter-anion, [Ir(C10H11N3)(C8H12)(C18H15P)]BF4, has been synthesized and structurally characterized. The cationic complex exhibits a distorted square-planar environment around the IrI ion. One significant non-standard hydrogen-bonding inter-action exists between a hydrogen atom on the N-heterocyclic carbene ligand and a fluorine atom from the counter-ion, BF4 -. In the crystal, π-π stacking inter-actions are observed between one of the phenyl rings and the triazole ring. Both inter-molecular and intra-molecular C-H⋯π(ring) inter-actions are also observed.
