Bottom Line: The central Ru(II) atom adopts a distorted octa-hedral coordination sphere with two 2,2'-bi-pyridine (bpy) and one quinoline-2-carbaldehyde (pyridine-2-carbon-yl)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.In the crystal, the quinoline moiety of HL shows the shortest π-π stacking inter-action with the pyridine substituent of HL in a neighbouring complex, the centroid-to-centroid distance being 3.793 (3) Å.

ABSTRACT
The title compound, [Ru(C10H8N2)2(C16H12N4O)](BF4)2·3CH2Cl2, crystallizes with one complex dication, two BF4 (-) counter-anions and three di-chloro-methane solvent mol-ecules in the asymmetric unit. The central Ru(II) atom adopts a distorted octa-hedral coordination sphere with two 2,2'-bi-pyridine (bpy) and one quinoline-2-carbaldehyde (pyridine-2-carbon-yl)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 intra-molecular hydrogen bond with the quinoline-N atom. In the crystal, the quinoline moiety of HL shows the shortest π-π stacking inter-action with the pyridine substituent of HL in a neighbouring complex, the centroid-to-centroid distance being 3.793 (3) Å.

Mentions: The asymmetric unit of compound (I) contains one complex dication (Fig. 1 ▸), two BF4− counter-anions and three di­chloro­methane solvent mol­ecules. In the cationic complex, the neutral hydrazone is present as its Z isomer and coordinates to the RuII atom through the amide-O and imine-N atoms, forming a virtually planar five-membered chelate ring [maximum deviation from the least-squares plane = 0.015 (4) Å], as well as two bidentate bpy co-ligands. An intra­molecular hydrogen bond between the hydrazone N—H group and the quinoline-N atom is observed (Table 1 ▸). The pyridine (py) and quinoline (qn) moieties of HL are non-coordinating, but their mean planes are almost co-planar to the RuII carb­oxy­lic acid hydrazide (CAH: —C(O)NHN=) chelating plane. The dihedral angles between these planes are: py vs CAH = 5.4 (2), qn vs CAH = 3.7 (2) and py vs qn = 2.3 (2)°.
