Abstract

The complex mer,trans-[Ru(NO₂)(trpy)(PPh₃)₂ ⁺][PF^-₆] crystallizes in the centrosymmetric monoclinic space group P2₁/n with Z = 4; the ruthenium atom lies close to y = 1/4 and all data with h + l = 2n + 1 are systematically weak. The trpy ligand is not strictly planar, but has a "dish-like" geometry. The nitro ligand is rotated from the plane of the Ru(trpy) moiety, the N₃Ru/NO₂ interplanar angle being 32.5°. Ruthenium-ligand distances are: Ru-PPh₃ = 2.418(4) Å and 2.429(4) Å, Ru-NO₂ = 2.063(12) Å, Ru-N(trpy, outer) = 2.100(12) Å and 2.116(12) Å and Ru-N(trpy, central) = 2.004(11) Å.
