Abstract

The complex mer,trans-[Ru(NO₂)(trpy)(PPr₃)⁺ ₂][ClO^-₄]crystallizes in the centrosymmetric orthorhombic space group Pnma with Z = 4. Both the ruthenium(II) cation and the perchlorate ligand lie about crystallographic mirror planes. The nitro ligand is not coplanar with the Ru(trpy) moiety and suffers from two fold disorder about its Ru-N bond such that the two sets of oxygen atoms have symmetry-related sites above or below the crystallographic mirror plane. The n-propyl groups within the PPr₃ ligands suffer from disorder of their C(α) and C(β) atoms but share common C(γ) sites. Ruthenium-ligand distances are: Ru-PPr₃ = 2.398(2)Å, Ru-NO₂ = 2.053(7)Å, Ru-N(trpy, outer) = 2.078(6) and 2.092(6)Å and Ru-N(trpy, central) = 1.965(6)Å.
