In the title compound, [Ir(C11H8N)2(C28H20N8)](PF6)3·3CH3CN or [Ir(III)(ppy)2{(2-pym)2qpy(2+)}](PF6)3·3CH3CN (ppy = deprotonated 2-phenyl-pyridine, pym = pyrimidyl and qpy = 4,4':2',2'':4'',4'''-quaterpyrid-yl), the Ir(3+) cation is coordinated by two C atoms and four N atoms in a slightly distorted octa-hedral geometry. The asymmetric unit consists of one complex trication, three hexa-fluorido-phosphate anions and three aceto-nitrile solvent mol-ecules. The average Ir-C distance is 2.011 (14) Å, the average Ir-N(ppy) distance is 2.05 (6) Å and the average Ir-N(qpy) distance is longer at 2.132 (10) Å. The dihedral angles within the 4,4'-bipyridyl units are 31.5 (6) and 23.8 (7)°, while those between the 2-pym and attached pyridyl rings are rather smaller, at 11.7 (9) and 7.1 (9)°. The title compound was refined as a two-component inversion twin.
