Synthesis and crystallization
To a suspension of [(η6-p-cymene)Ru(μ –Cl)Cl]2 (0.2 mmol) in methanol (20 mL) was added 2,5-dichlorophenyl(pyridin-2-yl) methylene amine (0.42 mmol). The mixture was stirred at room temperature for 3 h followed by the reduction of the solvent volume in vacuo to about (10 mL) before adding NaBF4 (0.42 mmol). The mixture was then cooled in an ice bath while stirring for 2 h leading to a precipitate which was collected by filtration. The filtrate was washed with diethyl ether and dried in vacuo. Crystals were obtained by slow diffusion of hexane in a solution of the title compound in acetone over 2 days.

Experimental details
The methyl groups were idealized and refined using rigid groups allowed to rotate about the C—C bond (AFIX 137 option of the SHELXL-2013 program [12]). The Uiso values of the hydrogen atoms of methyl groups and the aromatic protons were set to 1.5Ueq(C). All other hydrogen atoms were also included using a riding model.
Discussion
Piano-stool complexes have applications in catalysis, supramolecular assemblies, molecular devices and have shown antiviral, antibiotic and anticancer activities [1, 2] . Three-legged piano stool complexes of Ru possess a pseudo octahedral geometry at the ruthenium atom arene ligand occupying three coordinating sites (the seat) with three other ligands. Their unique properties, which includes the mild reaction conditions required for their synthesis, high yields and good stability and solubility under aqueous conditions have enabled them be of interest in organometallic chemistry [3]. The coordinated arene ligands are relatively inert towards substitution and act as spectator ligands [3]. They stabilize and protect the metal centre and thereby prevent rapid oxidation of the Ru(II) to Ru(III) [4].
The title compound is part of our continuing studies of half-sandwich ruthenium(II) complexes [5], [6], [7], [8], in which the cationic species of the complex feature the known “pseudo-octahedral three-legged piano stool” structure. As expected, the ruthenium centre is coordinated to the N,N′-bidentate ligand through the nitrogen atoms and the chlorido ligand and the three atoms serve as the base of the piano stool. The p-cymene ring occupies the remaining coordination sites of the Ru(II) center and serve as the seat of the stool. The Ru—N bond lengths are 2.061(15) and 2.082(15) Å. These values are comparable to those reported for other arene ruthenium complexes with N,N′-ligands [5], [6], [7]. The N—Ru—N bond angles are 76.48(6)° while the N—Ru—Cl bond angles are 83.89(5) and 84.05(5)° and are also close to those values reported for related compounds [5; 6; 7, 9, 10].
