Abstract

The title compound, [Ru(C₁₀H₈N₂)₂(C₁₆H₁₂N₄O)](BF₄)₂·3CH₂Cl₂, crystallizes with one complex dication, two BF₄^- counter-anions and three dichloromethane solvent molecules in the asymmetric unit. The central Ru^II atom adopts a distorted octahedral coordination sphere with two 2, 2′-bipyridine (bpy) and one quinoline-2-carbaldehyde (pyridine-2-carbonyl)hydrazone (HL) ligand. The hydrazone ligand has a Z form and coordinates to the Ru^II atom via the amide-O and imine-N atoms, affording a planar five-membered chelate ring, while its pyridine-N and quinoline-N donor atoms in the substituents are non-coordinating. The hydrazone N - H group forms an intramolecular hydrogen bond with the quinoline-N atom. In the crystal, the quinoline moiety of HL shows the shortest π-π stacking interaction with the pyridine substituent of HL in a neighbouring complex, the centroid-to-centroid distance being 3.793 (3) Å.
