The 13H15N2S2)[RuCl3(C10H14)], contains a 1,3-(2-thienylmethyl)-4,5-dihydroimidazolium cation and a trichlorido(η6-p-cymene)ruthenate(II) anion. The thiophene rings of the cation are disordered by an 180° rotation about the thiophene–CH2 bonds with occupancies of 0.847 (5)/0.153 (5) and 0.700 (5)/0.300 (5), respectively. The Ru atom exhibits a distorted octahedral coordination with the benzene ring of the p-cymene ligand formally occupying three sites and three Cl atoms occupying the other three sites. The short C—N bond lengths in the imidazoline ring indicate partial electron delocalization within the N—C—N fragment. Cation and anions are connected through five intermolecular C—H⋯Cl hydrogen bonds and one C—H⋯π hydrogen bond, forming a three-dimensional hydrogen-bonded network.

A suspension of 1,3-bis(thiophen-2ylmethyl)-,4,5-dihydro-1H-imidazolium 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 (Fig. 3). The reaction mixture was then filtered while hot, and the volume was reduced to about 10 ml before addition of n-hexane (15 ml). The precipitate formed was crystallized from CH2Cl2: hexane (5:10 ml) to give the complex as red-brown crystals. Yields: 0.208 g, 69%. M.p.: 227–228°C. 1H NMR(CDCl3) δ: 1.39 (d, 6H, J = 6.9 Hz, CH3(C6H4)CH(CH3)2), 2.29 (s, 3H, CH3(C6H4)CH(CH3)2), 3.21 (m, 1H, CH3(C6H4)CH(CH3)2), 3.79 (s, 4H, NCH2CH2N), 4.12 (s, 4H, CH2C4H3S), 5.29 and 5.58 (d, 4H, J = 5.8 Hz, CH3(C6H4)CH(CH3)2), 7.03–7.68 (m, 6H, C4H3S), 8.99 (s, 1H, 2-CH). 13C NMR (CDCl3) δ: 18.6 (CH3(C6H4)CH(CH3)2), 22.3 (CH3(C6H4)CH(CH3)2), 30.8 (CH3(C6H4)CH(CH3)2), 47.0 (NCH2CH2N), 47.1 (CH2C4H3S), 79.6, 81.8, 96.5 and 100.8 (CH3(C6H4)CH(CH3)2), 126.7, 127.5, 129.1 and 135.2 (C4H3S), 159.3 (2-CH). Anal. Calc. for C23H29S2N2RuCl3: C, 45.66; H, 4.83; N, 4.63%. Found: C, 45.71; H, 4.89; N, 4.69%.
All H atoms attached to carbons were geometrically fixed and allowed to ride on the corresponding non-H atom with C—H = 0.96 Å, and Uiso(H) = 1.5Ueq(C) of the attached C atom for methyl H atoms and 1.2Ueq(C) for other H atoms.

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. |

Metal-carbene compounds, such as N-heterocyclic carbene palladium and ruthenium complexes, are important catalysts that have a wide range of applications such as Suzuki-Miyaura, Sonogashira, Stille and Heck reactions (Herrmann 2002; Herrmann et al., 1995; Navarro et al., 2006; Arduengo & Krafczyc, 1998).
In previous papers, we have described the synthesis, characterization and applications of palladium, platinum and ruthenium N-heterocyclic carbene complexes as catalysts (Yaşar et al., 2008; Arslan et al., 2007, 2005a, 2005b, and references therein; Özdemir et al., 2008, 2007, 2005, and references therein). In view of these important attributes of N-heterocyclic carbene derivatives, we report here the crystal structure of one of them. The title compound consists 1,3-bis(thiophen-2-ylmethyl)-4,5-dihydro-1H-imidazolium cation and a trichloro(η6-p-cymene) ruthenium(II) anion. The molecular structure of the title compound, (I), is depicted in Fig. 1. Cation and anion groups are connected with five intermolecular C—H···Cl hydrogen bonds and one C—H···π hydrogen bond, forming a three-dimensional hydrogen-bonding network (Fig. 2).
A flip disorder of both thiophene rings in 1,3-bis(thiophen-2-ylmethyl)-4,5-dihydro-1H-imidazolium cation is observed. There are two positions of both thiophene rings, rotated by 180°. The crystal structure of the cation contains four disordered atoms, S1, S2, C16, and C21. The site occupancy factors refined to 0.847 (5) and 0.153 (5) for the S1—C15—C16—C17—C18 ring, and 0.700 (5) and 0.300 (5) for the S2—C20—C21—C22—C23 ring. A similar thiophene ring disorder has been observed in some thiophene derivatives, such as (Z)-3-(1-methyl-1H-indol-3-yl)-2-(thiophen-3-yl)acrylonitrile (Sonar et al., 2004), (Z)-2-(3-thienyl)-3-(3,4,5-trimethoxyphenyl)acrylonitrile (Sonar et al., 2005a), (Z)-3-(1H-Indol-3-yl)-2-(3-thienyl)acrylonitrile and (Z)-3-[1-(4-tert-butylbenzyl)-1H-indol-3-yl]-2-(3-thienyl)acrylonitrile (Sonar et al., 2005b), 1,2-di-3-thienyl-2-hydroxyethanone(3,3-thenoin) (Crundwell et al., 2002), 3-[2-(anthracen-9-yl)ethenyl] thiophene, (Wagner et al., 2006a), 2,5-bis(2-cyano-2-thienylvinyl)thiophene (Wagner et al., 2006b), and 1,4-diphenyl-2,3-dithien-3-ylcyclopentadien-1-one (Linehan et al., 2003). In addition, all thiophene rings in the cation are almost planar; the maximum deviations from the least squares planes are 0.019 (4)Å for C16 and 0.006 (6)Å for C22.
The coordination geometry of ruthenium is pseudooctahedral, with an average Ru—Cl bond distance of 2.430Å. 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 other three sites. The distance between the centroid of the p-cymene ring and ruthenium is 1.6493 (15) Å, which is longer than that 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).
The imidazolidine ring is almost planar, the deviations from planarity of ring are N1 0.002 (3), C11 0.001 (4), N2 0.004 (3), C12 0.005 (4), C13 0.004 (4)Å. The some C—N bond lengths (N1—C11 = 1.307 (4)Å and N2—C11 = 1.302 (4)Å) for the imidazolidine ring are shorter than the average single C—N bond length of 1.48Å, thus showing double bond character in these C—N bonds. The other CN bonds length (N1—C13 1.458 (5), N1—C14 1.462 (4), N2—C19 1.460 (4) and N2—C12 1.466 (4)Å) is agree with 1.48Å C—N single bond lengths. This information indicates a partial electron delocalization within the N1—C11—N2 fragment.
The crystal packing is shown in Fig. 2. Five intermolecular C—H···Cl hydrogen bonds link the molecules of (I) and generate a three-dimensional hydrogen bonded framework. In addition, a C14 (x, y, z)-H···π (S2—C20—C21—C22—C23, thiophene ring; 1 - x, 1 - y, 2 - z) hydrogen bond is observed in the title compound, Table 1.
