4,6,7,9,10,12-Hexahydro-1,3-dithiolo[4,5-f][1,4,9]oxadithia­cyclo­undecine-2-thione

Abstract

In the title mol­ecule, C₉H₁₂S₅O, the five-membered ring and attached S atom are essentially coplanar [mean deviation from the mean plane = 0.020 (1) Å]. The two S atoms belonging to the macrocycle deviate from this plane by 1.005 (1) and 1.337 (2) Å. In the crystal, π–π inter­actions link the mol­ecules into centrosymmetric dimers with a short distance of 3.753 (5) Å between the centroids of the five-membered rings.

Comment

Crown ether annulated 1,3-dithiol-2-thione derivatives have been intensively investigated as key intermediate of the crowned tetrathiafulvalenes because the latter molecules show electrochemical signaling for various metal cations (Hansen et al.,1992; Trippé et al., 2002). We report hererin the crystal structure of the title compound, (I).

In (I) (Fig. 1), five-membered ring and attached S2 atom are essentially coplanar with the mean deviation of 0.020 (1) Å from the mean plane P. The plane defined by the rest non-hydrogen atoms forms an angle of 70.25 (4) ° with P. The π-π interactions with the short distance of 3.753 (5) Å between the centroids of five-membered rings link the molecules into centrosymmetric dimers.

Experimental

The title compound was prepared according to the literature (Chen et al., 2005). Single crystals suitable for X-ray diffraction were prepared by slow evaporation a mixture of dichloromethane and petroleum at room temperatue.

Refinement

Carbon-bound H-atoms were placed in calculated positions with C—H 0.97 Å and were included in the refinement in the riding model, with U_iso(H) = 1.2 U_eq(C).

Special details

Experimental. (See detailed section in the paper)

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.
