Dibromido(⁵-pentamethylcyclopentadienyl)(5-phenyldibenzophosphole-P)iridium(III) dichloromethane solvate

M. Kotera and T. Suzuki

Abstract: 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-phenyldibenzophosphole compared with PPh₃. The dibenzophosphole portion of the ligand is nearly planar, and the planes of the dibenzophosphole units of neighbouring molecules are stacked on top of each other to form a dimer in the crystal structure. The closest CC distances between the planes are 3.9 Å.
