The 14H17N2S2)[Ru(C10H14)Cl3], contains a 1,3-bis(thiophen-2-ylmethyl)-3,4,5,6-tetrahydropyrimidinium cation and a trichlorido(η6-p-cymene)ruthenate(II) anion. The Ru atom exhibits a distorted octahedral coordination with the benzene ring of the p-cymene ligand formally occupying three sites and three chloride atoms occupying the other three sites. The N—C bond lengths of the N—C—N unit of the pyrimidinium cation are shorter than the average single C—N bond length of 1.48 Å, thus showing double-bond character, indicating a partial electron delocalization within the N—C—N fragment. The pyrimidine ring has an Four intermolecular C—H⋯Cl hydrogen bonds generate a three-dimensional hydrogen-bonded framework.

A suspension of 1,3-bis(thiophen-2ylmethyl)-3,4,5,6-tetrahydropyrimidinium chloride (1.1 mmol), Cs2CO3 (1.2 mmol) and [RuCl2(p-cymene)] (0.5 mmol) was heated under reflux in degassed toluene (20 ml) for 7 h. The reaction mixture was then filtered while hot, and the volume was reduced to about 10 ml before addition of n-hexane (15 ml) (Scheme 2). The precipitate formed was crystallized from CH2Cl2/diethylether (5:15 mL) to give complex as red-brown crystals. Yields: 0.232 g; 75%.

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. |

N-heterocyclic carbene ligands have emerged as one of the most important classes of compounds used for catalytic reactions such as Suzuki-Miyura, Sonogashira, Stille and Heck reactions (Herrmann et al., 1995; Navarro et al., 2006; Arduengo & Krafczyc, 1998; Herrmann, 2002; Littke & Fu, 2002). Recently, we have focused on the synthesis, characterization and application of palladium, platinum and ruthenium N-heterocyclic carbene complexes as catalysts (Yaşar et al., 2008; Arslan et al., 2007a, 2007b,2007c, 2004a, 2004b, 2005a, 2005b).
To continue our studies on this topic (Özdemir et al. (2005a, 2005b, 2005c, 2007, 2008)), we report herein the X-ray crystal structure of an N-heterocyclic carbene cation (1,3-bis(thiophen-2-ylmethyl)-3,4,5,6-tetrahydropyrimidinium) and trichloro(η6-p-cymene)ruthenat(II) anion compound. The molecular structure of the title compound, (I), is depicted in Fig. 1.
The structure of the title compound consists of [C14H17N2S2]+ cations and [C10H14Cl3Ru]- anions. These groups are connected with four intermolecular C—H···Cl hydrogen bonds, thus forming a three-dimensional hydrogen-bonded network (Fig. 2). The intermolecular contacts are also listed in Table 1.
The thiophene rings are almost planar, while the pyrimidin ring is not planar. The deviations from planarity for the pyrimidin ring are C1 0.111 (4), N1 0.013 (3), C2 0.207 (4), C3 0.328 (4), C4 0.229 (4), and N2 0.010 (3) Å. The puckering parameters (Cremer & Pople, 1975) and the smallest displacement asymmetry parameters (Nardelli, 1983) for the pyrimidin ring are Q = 0.464 (4) Å, Θ = 55.1 (5) ° and ϕ = 236.6 (5)°, q2 = 0.381 (4) Å, and ΔC2(C1) = 2.8 (4), ΔCs(C1) = 66.6 (3). According to these results, the pyrimidin ring adopts an envelope conformation.
The coordination geometry of ruthenium is pseudooctahedral, with an average Ru—Cl bond distance of 2.427 Å. The ruthenium atom exhibits a distorted octahedral coordination with the benzene ring of the p-cymene ligand formally occupying three sites and three chloride atoms occupying three other sites. The distance between the centroid of the p-cymene ring and ruthenium atom is 1.972 (3) Å, which is longer than reported in other Ruthenium compounds (Liu et al., 2004; Therrien et al., 2004). All the other bond lengths in (I) are in normal ranges (Allen et al., 1987).
Some C—N bond lengths (N1—C1 = 1.313 (4) Å and N2—C1 = 1.312 (4) Å) for the 1,3-bis(thiophen-2-ylmethyl)-3,4,5,6-tetrahydropyrimidinium cation are shorter than the average single C—N bond length of 1.48 Å, thus showing double bond character in these C—N bonds. The other C—N bond lengths (N1—C2 1.468 (4), N1—C10 1.475 (4), N2—C5 1.466 (4) and N2—C4 1.469 (4) Å) are in agreement with the expected 1.48 Å C—N single bond lengths. This information indicates a partial electron delocalization within the N1—C1—N2 fragment.
