摘要：

In the title compound, [IrCl(C8H12)(C17H25N3)], the Ir-I ion has a distorted square-planar coordination geometry. The N-heterocyclic carbene ligand has an extended S-shaped conformation. The butyl group was refined using a two-part 1:1 disorder model. In the crystal, three unique weak C-H center dot center dot center dot Cl contacts are present. Two of these form a motif described as R-2(1) (6) in graph-set notation, while a third forms an R-2(2) (8) motif about a crystallographic inversion center. The result is a chain structure which extends parallel to the crystallographic a axis.
