Abstract
In the crystal structure of the title compound, C12H18S5, no significant intermolecular π–π interactions are found. Weak intermolecular C—S⋯π [S⋯centroid = 3.787 (1) Å] interactions and van der Waals forces may be effective in the stabilization of the structure.

Comment
Since the discovery of the first organic metal TTF-TCNQ (TTF: tetrathiafulvalene TCNQ: 7,7,8,8-tetracyanoquinodimethane) (Ferraris et al., 1973) organic electron donors with a TTF backbone have been widely investigated in terms of synthetic and structural as well as physical aspects (Williams et al., 1992). The most conventional route to these electron donors is based on the coupling of 1,3-thiole-2-thione (one) derivatives promoted by trialkyl phosphite (Bechgaard et al., 1975; Engler et al., 1977; Kini et al., 1999; Li et al., 2000). Thus, the key precursors to these TTF-based electron donors are 1,3-thiole-2-thione (one) derivatives. Among them, 4,5-bisalkylthio-1,3-dithiole-2-thione can be routinely prepared by the reaction between a zinc complex of 1,3-dithiole-2 -thione-4,5-dithiolate or the anion 1,3-dithiole-2-thione-4,5-dithiolate generated in situ and suitable electrophilic reagents (Svenstrup & Becher, 1995). Thus the interest in the synthesis of various 1,3-dithiole-2-chalcogenone is evident and promoted us to take up this project. In continuation of our work in this field, we report herein the crystal structure of title ligand, (I).
In the molecule of (I) (Fig. 1), the bond lengths are within normal ranges (Allen et al., 1987).
In the crystal structure, no significant intermolecular π–π interactions are observed. Weak intermolecular C—S···π interactions, with S1···Cg1 = 3.787 (1) Å [Cg1 denotes centroid of cyclotridecine ring; (S1/S4/C1/C2/C12), symmetry code: -1 + x, y, z] and van der Waals forces stabilize the crystal structure.
Experimental
The synthesis of (I) was carried out via the coupling of 1,9-dibromooctane (1 mmol) with the zinc complex of 1,3-dithiole-2-thione-4,5-dithiolate (0.5 mmol) in acetone (5 ml) at 293 K. The color of the mixture was turned from red to yellow. The pure compound was obtained in 32% yield by washing of the crude product with chloroform, in which it is highly soluble (Kumar et al., 1998).
Refinement
H atoms were positioned geometrically, with C—H = 0.99 Å for methylene H, and constrained to ride on their parent atoms, with Uiso(H) = 0.050 (2) Å2.

Special details
| 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. |
