Synthesis, crystal structure and Hirshfeld surface analysis of [bis­­(di­phenyl­phosphan­yl)methane-κP]chloridobis­[2-(pyridin-2-yl)phenyl-κ2N,C1]iridium(III)

The title IrIII complex, [Ir(C11H8N)2Cl(C25H22P2)], was synthesized from the substitution reaction between the (ppy)2Ir(μ-Cl)2Ir(ppy)2 (ppy = deprotonated 2-phenyl­pyridine, C11H8N−) dimer and 1,1-bis­(di­phenyl­phosphan­yl)methane (dppm, C25H22P2) under an argon gas atmosphere for 20 h. The IrIII atom is coordinated by two C,N-bidentate ppy anions, a unidentate dppm ligand and a chloride anion in a distorted octa­hedral IrC2N2PCl arrangement. The N donor atoms of the ppy ligands are mutually trans while the C atoms are cis. Intra­molecular aromatic π–π stacking between the phenyl rings of ppy and dppm, and C—H⋯Cl inter­actions are observed. In the crystal, C—H⋯Cl and C—H⋯π contacts link the mol­ecules into a three-dimensional network. A Hirshfeld surface analysis was carried out to further qu­antify the inter­molecular inter­actions, and indicated that H⋯H contacts (63.9%) dominate the packing.
