The non-coordinated dpqMe2 ligand crystallizes in the centrosymmetric space group P21/a (Wozniak et al., 1993). Other arene–ruthenium and osmium complexes with chelating quinoxaline pyridyl derivatives have been synthesized and characterized by X-ray structure analysis (Baumann et al., 1998; Scott et al., 1999; Lalrempuia & Kollipara, 2003; Therrien et al., 2007).

The dinuclear complex [(η6-1,2,4,5-C6H2Me4)Ru(µ-Cl)Cl]2 (70 mg, 0.11 mmol) is dissolved in methanol (50 ml). The resulting solution is added dropwise to a two-necked flask equipped with a reflux condenser and containing a methanol solution (50 ml) of dpqMe2 (71 mg, 0.23 mmol) and KPF6 (42 mg, 0.11 mmol). The mixture is heated to 50°C and stirred for 24 h. After cooling to room temperature, the volume is reduced and the product is precipitated by addition of diethylether. The orange solid is filtered, washed with n-pentane and dried under vacuo to give [(η6-1,2,4,5-C6H2Me4)RuCl(dpqMe2)][PF6] (130 mg, 0.12 mmol, yield 78.1%).
Crystals of (I) were obtained by the slow diffusion of diethylether into an acetonitrile solution of (I).

Calc. for C30H30N4ClF6PRu: C, 49.49; H, 4.15; N, 7.70. Found: C, 49.33; H, 4.26; N, 7.49.
The H atoms were included in calculated positions and refined using a riding model (including free rotation about the acetonitrile C—C bond), with C—H = 0.93–0.96 Å and with Uiso(H) = 1.2 (1.5 for methyl groups) times Ueq(C).
The title complex (I) shows a typical piano-stool geometry with the metal centre coordinated by the arene ligand, a terminal chloride and the chelating 6,7-dimethyl-2,3-di(pyridin-2-yl)quinoxaline (dpqMe2) ligand. In the mononuclear complex (I), the metal centre is stereogenic. However, since none of the ligand contains a chiral information, (I) is obtained as a racemic mixture.
The Ru—N bond distances 2.060 (2) and 2.077 (2) Å in (I) are comparable to those in [(η6-p-PriC6H4Me)RuCl(η2-2,3-bis(2-pyridyl)pyrazine)][BF4] (Singh et al., 2002) and [(η6-p-PriC6H4Me)RuCl(η2-2,3-bis(α-pyridyl)quinoxaline)][PF6] (Lalrempuia & Kollipara, 2003). Accordingly, there is no significant difference in the Ru—Cl bond length in (I) [2.3732 (9) Å] and reported values (Lalrempuia & Kollipara, 2003)(Scott et al., 1999)(Canivet et al., 2005). The N(1)—Ru(1)—N(2) bond angle in complex (I) [76.04 (9)°] is similar to those of complexes [(η6-p-PriC6H4Me)RuCl(η2-2,3-bis(2-pyridyl)pyrazine)]+ [N(1)—Ru(1)—N(2) = 76.5 (2)°] (Singh et al., 2002) and [(η6-p-PriC6H4Me)RuCl(η2-2,3-bis(α-pyridyl)quinoxaline)]+ [N(1)—Ru(1)—N(2) = 76.2 (2)°] (Lalrempuia & Kollipara, 2003). An ORTEP drawing with the atom labelling scheme for (I) is shown in Figure 1.
Upon formation of the mononuclear complex (I), the bond length between the connecting carbon atoms [C(5)—C(6) = 1.472 (4) Å] of the coordinated pyridyl and quinoxaline moieties of the dpqMe2 ligand is slightly reduced as compared to the corresponding connecting C—C atoms [C(7)—C(8) = 1.496 (4) Å] of the non-coordinated pyridyl quinoxaline moities. Similarly, the C—C distances [1.493 Å] in the free dpqMe2 are longer (Wozniak et al., 1993). These bond length changes are in agreement with a back-donation from the metallic fragments to the dpqMe2 system, thus increasing the inter-ring bond order (Baumann et al., 1998) (Berg et al., 2002).
The major distortion imposed on the dpqMe2 structure upon coordination is encountered by the pyridyl groups. In the free ligand the two equivalent pyridyl groups are twisted by 39.6° relative to the plane of the quinoxaline unit (Wozniak et al., 1993). However, in (I) the twist of the coordinated pyridyl unit is 22.7 (1)°, while the non-coordinated pyridyl group is twisted by 54.2 (1)° relative to the plane of the quinoxaline unit.
The non-coordinated dpqMe2 ligand crystallizes in the centrosymmetric space group P21/a (Wozniak et al., 1993). Other arene–ruthenium and osmium complexes with chelating quinoxaline pyridyl derivatives have been synthesized and characterized by X-ray structure analysis (Baumann et al., 1998; Scott et al., 1999; Lalrempuia & Kollipara, 2003; Therrien et al., 2007).

Experimental. A crystal was mounted at 173 K on a Stoe Image Plate Diffraction System (Stoe & Cie, 2000) 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. |

The title complex (I) shows a typical piano-stool geometry with the metal centre coordinated by the arene ligand, a terminal chloride and the chelating 6,7-dimethyl-2,3-di(pyridin-2-yl)quinoxaline (dpqMe2) ligand. In the mononuclear complex (I), the metal centre is stereogenic. However, since none of the ligand contains a chiral information, (I) is obtained as a racemic mixture.
The Ru—N bond distances 2.060 (2) and 2.077 (2) Å in (I) are comparable to those in [(η6-p-PriC6H4Me)RuCl(η2-2,3-bis(2-pyridyl)pyrazine)][BF4] (Singh et al., 2002) and [(η6-p-PriC6H4Me)RuCl(η2-2,3-bis(α-pyridyl)quinoxaline)][PF6] (Lalrempuia & Kollipara, 2003). Accordingly, there is no significant difference in the Ru—Cl bond length in (I) [2.3732 (9) Å] and reported values (Lalrempuia & Kollipara, 2003)(Scott et al., 1999)(Canivet et al., 2005). The N(1)—Ru(1)—N(2) bond angle in complex (I) [76.04 (9)°] is similar to those of complexes [(η6-p-PriC6H4Me)RuCl(η2-2,3-bis(2-pyridyl)pyrazine)]+ [N(1)—Ru(1)—N(2) = 76.5 (2)°] (Singh et al., 2002) and [(η6-p-PriC6H4Me)RuCl(η2-2,3-bis(α-pyridyl)quinoxaline)]+ [N(1)—Ru(1)—N(2) = 76.2 (2)°] (Lalrempuia & Kollipara, 2003). An ORTEP drawing with the atom labelling scheme for (I) is shown in Figure 1.
Upon formation of the mononuclear complex (I), the bond length between the connecting carbon atoms [C(5)—C(6) = 1.472 (4) Å] of the coordinated pyridyl and quinoxaline moieties of the dpqMe2 ligand is slightly reduced as compared to the corresponding connecting C—C atoms [C(7)—C(8) = 1.496 (4) Å] of the non-coordinated pyridyl quinoxaline moities. Similarly, the C—C distances [1.493 Å] in the free dpqMe2 are longer (Wozniak et al., 1993). These bond length changes are in agreement with a back-donation from the metallic fragments to the dpqMe2 system, thus increasing the inter-ring bond order (Baumann et al., 1998) (Berg et al., 2002).
The major distortion imposed on the dpqMe2 structure upon coordination is encountered by the pyridyl groups. In the free ligand the two equivalent pyridyl groups are twisted by 39.6° relative to the plane of the quinoxaline unit (Wozniak et al., 1993). However, in (I) the twist of the coordinated pyridyl unit is 22.7 (1)°, while the non-coordinated pyridyl group is twisted by 54.2 (1)° relative to the plane of the quinoxaline unit.
