Source of material

A suspension of [(h6-C6H6)Ru(m-Cl)Cl]2 (0.2 mmol) in methanol (20 mL) was added to a solution of (N-(2,6-dimethylphenyl)-1-(pyridin-2-yl)methanimine (0.42 mmol) in methanol. The mixture was stirred at room temperature for 3 h followed by the reduction of the solvent in vacuo to about 10 ml before adding NaClO4 (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 the liquid diffusion method in which the solutions of the title compound in acetone was layered with hexane and left undisturbed for 2 days.

Yield (85%), m.p. 250° (decomp.). 1H-NMR (400 mHz, DMSO-d6, 25 °C). δ = 9.67 (s, 1H, Py), 8.88 (s, 1H,CH = N), 8.32 (t, JHHH = 7.4 Hz, 1H, Py), 8.21 (d, JHH = 7.48 Hz, 1H, Py), 7.93–7.86 (m, 1H, Py), 7.34–7.27 (m, 3H, Ar), 5.87 (s, 6H, C6H6), 2.37 (s, 3H, Ar-CH3), 2.17 (s, 3H, Ar-CH3). 13C-NMR (400 mHZ, DMSO-d6, 25 °C) δ = 173. 59 (CH = N), 156.24 (Py), 153.95 (Py), 150.96 (Py), 140.12 (Py), 131.12 (Py), 130.03 (Ar), 129.3 (Ar), 128.99 (Ar), 128.70 (Ar), 128.23 (Ar), 87.21 (C6H6), 19.75 (Ar—CH3), 18.11 (Ar—CH3). MS (ESI, M/Z): 425.0363 for [C20H20ClN2Ru]+.

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 SHELX program system [12]). The coordinates of the H-atoms of the water molecule were refined with the O—H distance restrained to 0.848 and 0.846 Å. The Uiso values of the hydrogen atoms of methyl groups and the aromatic protons were set to 1.5Ueq(C), whereas the Uiso values of all other hydrogen atons were set to 1.2Ueq(C, N).

Discussion

The title compound was synthesized as part of a study of half sandwich ruthenium(II) complexes using N,N′-bidentate ligands to obtain stable compounds [1], [2], [3], [4]. There is an increasing interest in the chemistry of half-sandwich organo-ruthenium complexes due to their numerous applications in new catalytic systems [5]. In addition some ruthenium complexes with N,N′-bidentate ligands have also found application as anticancer agents [6].

The asymmetric unit contains one cationic ruthenium (II) complex, one perchlorate counter anion and one molecule of water. The complex, just like the ones in literature, has a pseudo-octahedral “piano stool” structure in which the aromatic ring moiety of the neutral p-cymene occupies three coordination sites as the seat while the bidentate N,N′-ligand and the chlorido ligand occupy the other coordination sites and are the legs of the piano stool. The N,N′-bidentate pyridine-imine ligand has two planes that are twisted around the imine bond reducing sterical effects of the p-cymene ligand [7]. The Ru-N bond lengths of the complex are 2.0884(11) and 2.0902(12) Å and compare well with those reported for similar arene ruthenium complexes with N,N′ donor ligands [1], [2], [3], [4, 7], [8], [9]. The N-Ru-N bond angle is 76.90(5)°. The N-Ru-Cl bond angles range was 82.05(3)–88.41(3)° like in related compounds [7], [8], [9], [10]. The water and the perchlorate anion are both involved in O—H⋯O hydrogen bonds.
