چکیده
In an asymmetric unit of the title compound, C(8)H(12)N(2)S(4), there are two crystallographically independent half mol-ecules lying on inversion centers. One of the mol-ecules is disordered over two positions with relative occupancies of 82.0 (2) and 18.0 (2) for the major and minor components. In the crystal structure, mol-ecules are linked into a three-dimensional framework via inter-molecular C-H⋯N hydrogen-bonding inter-actions.

The asymmetric unit of the title compound, C(9)H(14)OS(4), comprises two crystallographically independent mol-ecules with similar conformations. In each mol-ecule, an intra-molecular C-H⋯O hydrogen bond generates a six-membered ring, producing an S(6) ring motif. All of the six-membered dithia-cyclo-hexane rings adopt chair conformations. The crystal structure is stabilized by four inter-molecu...
