(Received 6 February 2013; accepted 8 March 2013; online 16 March 2013)

The mononuclear title complex, [VCl2O(C3H8S)2], features a VIV=O double bond [1.5845 (15) Å] in an overall trigonal–bipyramidal coordination environment defined by two Cl and the S atoms of two (CH3CH2)(CH3)S ligands. In the crystal, pairs of mol­ecules form centrosymmetric dimers via C—H⋯O hydrogen bonds between the methyl C—H group and the oxidovanadium O atom of a neighbouring mol­ecule.

The chemistry of the higher oxidation states of vanadium with neutral thioether ligands in discrete complexes remains relatively unexplored due to the instability of such complexes. Our research group has already carried out X-ray crystallographic determinations of lower oxidation state niobium complexes of the general formula [Nb2Cl6L12L2] (L1= L2= tetrahydrothiophene C4H8S (THT) (Kakeya, Fujihara, Kasaya et al., 2006) and dimethyl sulfide C2H6S (Kakeya, Fujihara & Nagasawa, 2006)) and (L1 = dimethyl selenide C2H6Se, L2 = C2H6S) (Matsuura et al., 2012). We report here the structure of [VOCl2(C3H8S)2] (I, Scheme I). The molecule has two Cl- and two EtMeS ligands (Fig. 1). Crystal structures have been reported for trigonal bipyramidal complexes formed when the water ligands in [VOCl2(H2O)2] are replaced by 8-hydroxyquinolinium chloride (Takano et al., 2009), bis(2-(2-pyridylamino)pyridinium) dichloride (Hartung et al., 2005), diethyl ether (Papoutsakis et al., 2004) and benzo-15-crown-5 (Azuma et al., 1994). The only trigonal bipyramidal complex containing S2- reported to date is [VOCl2(thiourea)2] (II, Bristow et al., 1989). In complex I, the O atom and two Cl- ligands occupy the equatorial positions and the two EtMeS ligands the axial positions of a distorted trigonal bipyramid. The S2—V1—S1 angle of 166.66 (2) o deviates from the ideal value of 180 o. The steric bulkness of the EtMeS ligand may be responsible for controlling the structure. The V—S distances, 2.4803 (9) and 2.4858 (9) Å, in our complex are slightly longer than that of 2.424 (1) Å in II. The average V—Cl distance and other geometrical parameters fall within the range of those in II. In the crystal, pairs of molecules form centrosymmetric R22(10) dimers (Bernstein et al., 1995) via C—H···O hydrogen bonds between the methyl C—H group and the O atom of oxidovanadium in a neighboring molecule (Fig. 2).

Experimental top

All the reactions were carried out under a dry argon atmosphere by using standard Schlenk tube techniques. Vanadium trichloride, VCl3 (1.0 g, 6.4 mmol), was suspended in CH2Cl2 (40 mL), and ethylmethyl sulfide (C3H8S, 1.7 mL, 19 mmol) added to the solution at room temperature. The mixture was stirred at room temperature for 2 d, during which time, a purple precipitate, probably of residual starting material, was generated gradually. This was removed by filtration. The resultant filtrate was concentrated to 5 mL before the addition of n-hexane (10 mL). The solution was then set aside in a freezer at 255 K. After several days, blue crystals grew in the solution. The product was too reactive with liquid water to exist at temperatures higher than 273 K even in solvent under an Ar atmosphere.

Refinement top

The H atoms were placed in calculated positions, with C—H = 0.98 (methyl) and 0.99 (methylene) Å , and refined using a riding model, with Uiso(H) = 1.5.(methyl) and 1.2 Ueq (methylene).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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.
