The title compound, [IrBr2(5-C10H15)(C18H13P)]·CH2Cl2, is the first example of an iridium(III) phosphole complex to be characterized by X-ray crystallographic analysis. The Ir - P bond length is 2.2828 (15) Å, which is shorter by 0.04 Å than that of the analogous PPh3 complex. This is indicative of the steric compactness of 5-phenyl-dibenzophosphole compared with PPh3. The dibenzophosphole portion of the ligand is nearly planar, and the planes of the dibenzophosphole units of neighbouring mol-ecules are stacked on top of each other to form a dimer in the crystal structure. The closest C⋯C distances between the planes are 3.9 Å.
