In the title compound, [Ru(NO2)(C19H13N5)(C18H15P)2]ClO4.C2H6O, the two phosphine ligands are in trans positions. The Ru atom and the imidazolylpyridine moiety are almost coplanar, with the fused ring of the imidazolyl groups somewhat bent from the plane due to the steric hindrance of the phosphine phenyl groups. The nitro ligand is coordinated so that the NO2 group is rotated 40.5 (1)° from the imidazolylpyridine plane.
