The crystal structure of the title compound, [Ru(C10H8N2S)2(C11H11N3S)](PF6)2·C2H3N, is composed of a bivalent octahedral RuII complex, two PF6- anions and an acetonitrile solvent molecule. Two PF6- units are found on a crystallographic binary axis, therefore contributing just one half each to the asymmetric unit cell. The structure displays a peculiar stereochemistry of the cation. Three bidentate ligands around the Ru centre, together with the coordination of the non-symmetric S atom, mean that these two atoms are chiral. This would lead to four stereoisomers, but only an enantiomeric pair was found in the analyzed sample.

Di-2-pyridylsulfide (dps), 2-pyridylmethyl-2'-(4-methylpyrimidyl)sulfide (pmprs) and cis-Ru(dps-N,N)2Cl2·2H2O were prepared according to the methods of Chachaty et al. (1976), Haviv et al. (1983) and Tresoldi et al. (2005), respectively. cis-Ru(dps-N,N)2Cl2·2H2O (0.195 g, 0.33 mmol) and pmprs (0.22 g, 3 mmol) were refluxed in ethanol–water (50 ml, 3:2) under N2 for 3 h. After filtration of the solution into water (80 ml) containing NH4PF6 (0.49 g, 1 mmol) a yellow precipitate was obtained. This was filtered, washed with water (30 ml) and dried overnight. The solid was then dissolved in acetone (15 ml), precipitated with diethyl ether (70 ml), washed with diethyl ether (30 ml) and dried over P4O10. Yellow crystals of (I) suitable for X-ray structure investigation were obtained from a solution in acetonitrile–ether (3:1) on standing for ca 3 d at 252 K. Analysis, C32H30F12N8P2RuS3 requires: C 37.91, H 3.05, N 11.05%; found: C 37.85, H 3.00, N 11.00%.
X-ray diffraction analysis gave a monoclinic crystal system for (I). The space group was assumed to be centrosymmetric during the data-reduction procedure, and confirmed by the subsequent analysis (Orpen et al., 1992). All H atoms were treated as riding, with alkyl C—H distances of 0.98, methyl C—H distances of 0.96 and aromatic C—H distances of 0.93 Å. Their isotropic displacement parameters were fixed by the riding-model technique to Uiso(H) = 1.5Ueq(C) for the methyl group and 1.2Ueq(C) for all others. Intensities were calculated by the profile-fitting procedure (Lehmann & Larsen, 1974). Few refinement troubles were caused, mainly by the intrinsic disorder of the two units in the special position. It was necessary to chose two sites for most of the F atoms and their complementary occupancy factors were obtained by refinement and then fixed.

Special details top
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. |

Coordination chemistry of flexible and hemilabile ligands, containing both inert and labile groups, is an active area of research (Slone et al., 1999; Vagg, 1987). N-Heterocyclic donors are often good ligands for many transition metal centres. Hybrid S/N/S ligands consisting of inert pyridine or bipyridine binding groups, connected to labile sulfur binding sites, show S—S switching in addition to S inversion (Abel et al., 1995, and references therein). Thioether ligands containing aromatic heterocyclic N, such as di-2-pyridylsulfide or di-2-pyrimidylsulfide (dps and dprs), usually bind metals in an N,N-bidentate fashion (Bruno et al., 1995, and references therein) and sometimes adopt N-monodentate coordination (Tresoldi et al., 1991, 1992), or N,N- (De Munno et al., 1993; Teles et al. 1999) or N,N,S-bridging coordination (Anderson & Steel, 1998). The flexibility and, in a few cases, the hemilability of dps have been assessed (Tresoldi et al., 1992; De Munno et al. 1993).
Recently, we have demonstrated that dps, under appropriate conditions, binds Ru in an N,S-chelate fashion, leaving one of the pyridine rings uncoordinated (Scopelliti et al., 2001). In such species, some dynamic processes occur, as shown by the temperature dependence of the NMR spectra, but only the restricted rotation of the uncoordinated ring could be studied, whereas the total dynamic stereochemistry remained unclear. On the other hand, we have demonstrated the presence of two invertomers as enantiomeric pairs, (ΔR, ΛS) and (ΔS, ΛR), and obtained quantitative information on the activation energy of the pyramidal inversion around the coordinated S atom (Tresoldi et al., 2002), as well as of the restricted rotation of the pendant ring (Baradello et al., 2004), when the RuII centre was N,S-chelated by thioether ligands based on pyridine or pyrimidine and benzyl or phenyl derivatives. We have now turned our attention to metal complexes containing unsymmetrical NSNN thioethers, and we are interested in studying the interchange processes between different conformations and distinct coordination species. In this paper, the reaction of 2-pyridylmethyl-2'-(4-methylpyrimidyl)sulfide (pmprs) with cis-Ru(dps-N,N)2Cl2 led to the title compound, [Ru(dps-N,N)2pmprs](PF6)2·C2H3N, (I).
The structure of (I) presents two asymmetric atoms, Ru1 and S34, the conventional absolute configurations of which are Δ and R, respectively. Since the space group is centrosymmetric, a racemic mixture crystallizes in the solid state (ΔR and ΛS enantiomers; Fig. 1). The asymmetric unit consists of one cationic complex, one acetonitrile solvent molecule, one entire hexafluorophosphate unit and two further halves of the same anion located on special positions (along the binary axis). The coordination geometry of the RuII ion is, as expected, distorted octahedral, with five N atoms and atom S34 as binding sites (Table 1 and Fig. 1). The distortion provoked by an N,S short-bite ligand has already been shown in similar derivatives (Scopelliti et al., 2001). In (I), this effect is not so dramatic, since the five-membered ring presents less strain than the previously analysed four-membered N,S short-bite ligand. This is evident from the geometric comparison of the parameters N—Ru—S [81.8 (1) versus 67.8 (2)°], Ru—N [2.123 (3) versus 2.080 (5) Å] and Ru—S [2.358 (1) versus 2.424 (2) Å] in (I) and the above-mentioned structure, respectively. On the other hand, this is confirmed by an analogue of (I) with the pmprs position occupied by a different 2-pyridylmethylarylsulfide ligand (Baradello et al., 2004). In this case, the geometrical parameters are very close to those measured for (I) [Ru—S 2.370 (1) Å, Ru—N 2.108 (3) Å and N—Ru—S 81.39 (9)°]. The ring formed by the chelation is in an envelope-like conformation, as shown by the puckering parameters (Cremer & Pople, 1975) calculated using the atom sequence from Ru1 to S34 [q2 = 0.489 (4) Å and ϕ2 = −37.2 (5)°]. All these data were also compared with Ag (Wang et al., 2001) and Cu (Sillanpää et al., 1994) structures with the symmetric multidentate ligand 2,6-bis(2-pyrimidinylthiomethyl)pyrimidine, which develop (asymmetrically) the same coordination bite shown by pmprs. However, for these structures the other coordination site leads to an enhancement of the distortion. In (I), the Ru—N distances are slightly affected by the pmprs ligand, with the N atoms trans to this group being closer to the metal (Table 1). However, none of the Ru—N distances deviate much from the values reported for similar structures (~2.110 Å).
The two dps ligands display their usual `twisted N,N' inside' conformation, as shown by Bruno et al. (1995), in order to chelate the metal via the lone-pairs of the N atoms. For (I), though, the dps bite angle looks wider with respect to the previously analysed structure Which? [N···N 2.952 (5) and 2.946 (5) Å, and N—Ru—N 89.0 (1) and 89.1 (1)°, for the first and second ligands, respectively]. This is due to the short bite of the pmprs ligand allowing the widening of the dps groups. The boat-like conformation of both dps rings generated through the above-mentioned chelation is shown by the puckering parameters [for ring Ru1/N1–N13, Q = 0.839 (2) Å, θ = 88.2 (2) and ϕ = 0.7 (2)°; for ring Ru1/N14–N26, Q = 0.904 (3) Å, θ = 92.4 (2) and ϕ = 175.7 (3)°].
Since there are no structural data available for either the free or the coordinated 2-pyridylmethyl-2'-(4-methylpyrimidyl)sulfide (pmprs) ligand, ab initio and density functional theory calculations were carried out, using GAUSSIAN98 (Frisch et al., 1998); full geometry optimizations were carried out using the 6–31+G(d,p) basis set in order to obtain comparable data and to study how the molecular geometry of pmprs is modified by coordination to a metal centre. As the hybrid B3LYP method generally works better than the Hartree–Fock one in reproducing the `real' molecular geometry, we compared these calculated values with the experimental X-ray data. As expected, the gas phase conformation of pmprs looks very different from the coordinated one, because of its great conformational flexibility. Nevertheless, we observed a general agreement between the structural parameters, except for the fragment involved in coordination to the metal; the bond distances S34—C35 [1.7728 Å] and S34—C33 [1.8476 Å], and bond angles C33—S34—C35 [103.17°] and N27—C32—C33 [116.14°], can be compared with experimental values for (I) in Table 1.
The crystal packing of (I) is mainly stabilized by intermolecular hydrogen interactions, the acceptor atoms of which are F atoms of the anionic units or the N atom of the solvent molecule, while the donors are several types of C—H groups of the cationic unit. In this way, the complex molecules are mainly held together in an ordered array by the anion and the solvent molecule (Table 2). Other weak dipolar intercation interactions further stabilize the overall solid state structure.
