Crystal structure of [1,1'''-bis-(pyrimidin-2-yl)-4,4':2',2'':4'',4'''-quaterpyridine-1,1'''-diium-κ(2) N (1'),N (1'')]bis-[2-(pyridin-2-yl)phenyl-κ(2) N,C (1)]iridium(III) tris-(hexa-fluorido-phosphate) aceto-nitrile tris-olvate.

In the title compound, [Ir(C11H8N)2(C28H20N8)](PF6)3·3CH3CN or [IrIII(ppy)2{(2-pym)2qpy2+}](PF6)3·3CH3CN (ppy = deprotonated 2-phenyl­pyridine, pym = pyrimidyl and qpy = 4,4′:2′,2′′:4′′,4′′′-quaterpyrid­yl), the Ir3+ cation is coordinated by two C atoms and four N atoms in a slightly distorted octa­hedral geometry. The asymmetric unit consists of one complex trication, three hexa­fluorido­phosphate anions and three aceto­nitrile solvent mol­ecules. The average Ir—C distance is 2.011 (14) A, the average Ir—N(ppy) distance is 2.05 (6) A and the average Ir—N(qpy) distance is longer at 2.132 (10) A. 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.
