The cationic complex in the title compound, [Ir(C 9 H 7 N 2 ) 2 (C 12 H 8 N 2 )]PF 6 , comprises two phenyl-pyrazole (ppz) cyclo-metallating ligands and one 1,10-phenanthroline (phen) ancillary ligand. The asymmetric unit consists of one [Ir(ppz) 2 (phen)] + cation and one [PF 6 ] - counter-ion. The central Ir III ion is six-coordinated by two N atoms and two C atoms from the two ppz ligands as well as by two N atoms from the phen ligand within a distorted octa-hedral C 2 N 4 coordination set. In the crystal structure, the [Ir(ppz) 2 (phen)] + cations and PF 6  - counter-ions are connected with each other through weak inter-molecular C-H⋯F hydrogen bonds. Additional C-H⋯ π inter-actions between the rings of neighbouring cations consolidate the three-dimensional network. Electron density associated with additional disordered solvent mol-ecules inside cavities of the structure was removed with the SQUEEZE procedure in PLATON [Spek (2015 ▸). Acta Cryst . C 71 , 9-18]. The given chemical formula and other crystal data do not take into account the unknown solvent mol-ecule(s). The title compound has a different space-group symmetry ( C 2/ c ) from its solvatomorph ( P 2 1 / c ) comprising 1.5CH 2 Cl 2 solvent mol-ecules per ion pair.
