Bis(2-phenyl-4,6-di-2-pyridyl-1,3,5-triazine-κ3N4,N5,N6)ruthenium(II) bis(hexafluoridophosphate)

Abstract

The asymmetric unit of the title compound, [Ru(C19H13N5)2](PF6)2, consists of an RuII complex cation and two hexafluoridophosphate anions. The RuII atom is coordinated by three N atoms from the two outer pyridine and the central triazine rings of each of two tridentate ligands in a distorted octahedral environment. The ligands are approximately orthogonal to one another, with a dihedral angle of 88.34 (2)° between planes through the three six-membered rings of the two ligands. The pendant phenyl substituents are almost coplanar with the triazine rings to which they are bound, with dihedral angles of 5.41 (9) and 14.90 (10)°. This is reflected in the previously reported photophysical results with an increased lifetime of the triplet metal to ligand charge transfer (3MLCT) excited state [Fang, Taylor, Hanan, Loiseau, Passalacqua, Campagna, Nierengarten & Van Dorsselaer (2002).
