The single-crystal X-ray structure analysis of [RuCl2(C12H18)(C5H7NO)] reveals a distorted piano-stool geometry around the RuII atom, with a hexamethylbenzene ligand, two chloride ligands and a furfurylamine ligand, the latter coordinating through the amine group. In the crystal, a dimeric structure is observed as a result of N—H⋯Cl interactions between two symmetry-related molecules.

Furfurylamine was purchased from Aldrich and used as received and [(η6-C12H18)Ru(µ-Cl)Cl]2 (Bennett et al., 1982) was prepared according to published methods. The NMR spectrum was recorded on a Bruker 400 MHz spectrometer. The infrared spectrum was recorded on a Perkin-Elmer 1720X FT—IR spectrometer (4000–400 cm-1).
A mixture of [(η6-C12H18)Ru(µ-Cl)Cl]2 (90 mg, 0.135 mmol) and two equivalents of furfurylamine (24 µL, 0.27 mmol) was stirred in dichloromethane (10 ml) for 2 h at room temperature. The orange-red compound which formed was filtered, washed with diethyl ether and dried under vacuum (Yield 98%).
Crystals suitable for X-ray
were obtained, after days, by slow diffusion of diethyl ether into a dichloromethane solution of the title complex.1H NMR (400 MHz, CDCl3): 7.35 p.p.m. (d, 3J = 2 Hz, 1H, Hγ), 6.29 (dd, 1H, Hβ), 6.20 (d, 3J = 2 Hz, 1H, Hα), 3.96–3.92 (m, 2H, CH2), 2.97 (br, 2H, NH2), 2.15 (s, 18H, CH3).
IR (KBr pellet): νNHasym 3295 s, νNHsym 3194 m, νCOC 1159 m, νCOC 1000 m cm-1.
All H atoms were included in calculated positions (C—H = 0.93 Å for Carom, 0.97 Å for CH2, 0.96 Å for CH3; N—H = 0.90 Å for NH2) and treated as riding atoms with the constraint Uiso(H) = 1.2 (1.5 for methyl) Ueq(carrier) applied.

Experimental. A crystal was mounted at 173 K on a Bruker SMART CCD PLATFORM using Mo Kα graphite monochromated radiation. Image plate distance 70 mm, ϕ oscillation scans 0 - 200°, step Δϕ = 1.0°, 3 minutes per frame. |
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Arene ruthenium(II) complexes are promising antitumoral and antimetastatic agents (Süss-Fink, 2010; Therrien & Smith, 2011), and furfuryl derivatives are known to possess antimetabolite (Hamann et al., 1968) and antibacterial properties (Shi et al., 2008). The synthesis of dichlorido(furfurylamine-κN)(η6-hexamethylbenzene)ruthenium(II) is presented. However, a biological evaluation was not possible due to the low water-solubility of the compound.
The formation of (η6-C12H18)RuCl2(C5H7NO-κN) is easily monitored by 1H NMR spectroscopy, in which the signal corresponding to the protons of the NH2 group is strongly shifted by 1.57 p.p.m., while the signal of the CH2 protons is also shifted downfield but to a lesser extent (0.15 p.p.m.) as compared to uncoordinated furfurylamine. The infrared spectrum of (η6-C12H18)RuCl2(C5H7NO-κN) shows as well shifting of some of the bands associated to the furfurylamine moiety, especially those corresponding to the symmetrical and asymmetrical νNH, in accordance with other metal complexes of furfurylamine derivatives (Joesten et al., 1967). In addition, the molecular structure of the complex has been established by single-crystal structure analysis.
The title complex shows a three-legged piano-stool geometry with the RuII metal center being surrounded by an hexamethylbenzene ligand, two terminal chlorido and a N-coordinated furfurylamine ligand, see Fig. 1. The furfurylamine acts as a monodentate ligand and the Ru—N distance at 2.156 (2) Å is comparable to the one found in the analogous dichlorido(η6-p-cymene)(benzylamine-κN)ruthenium(II) complex [2.1445 (18) Å] (Govindaswamy et al., 2004). The aromatic ring of the hexamethylbenzene is planar and the Ru-centroid distance is 1.672 Å (centroid defined by C6 to C11). Otherwise, the Ru—Cl distances are almost equivalent at 2.4277 (9) and 2.4299 (8) Å, respectively, which is similar to those found in other dichlorido arene ruthenium complexes (Therrien & Süss-Fink, 2004; Govindaswamy et al., 2004; Therrien et al., 2004).
In the crystal packing, one chlorido is involved in an H-bonded interaction with the NH2 moiety of a neighbouring molecule, thus forming a centrosymmetric dimeric structure: The N—Cl separations being 3.406 (3)Å with the N—H···Cl angles being 168.3°.
