A hybrid bidentate and tridentate ruthenium(II) complex incorporating triazine and polypyridine carbene ligands

The title compound, (acetonitrile)[4-(4-bromo­phen­yl)-2,6-di-2-pyridyl-1,3,5-triazine](1,3-di-2-pyridyl-2,3-dihydro-1H-imidazol­yl)­ruthenium(II) bis­(hexa­fluoro­phosphate) aceto­nitrile hemisolvate [Ru(C₂H₃N)(C₁₉H₁₂BrN₅)(C₁₃H₁₀N₄)](PF₆)₂·0.5C₂H₃N, was synthesized incorporating a tridentate triazine-based ligand and a bidentate carbene-based poly­pyridine ligand. Bidentate coordination is favoured due to steric strain enforced by the five-membered ring in the carbene ligand, leaving one uncoordinated pyridyl ring. An acetonitrile mol­ecule completes the distorted octa­hedral geometry.
