چکیده
The title unsymmetrical tetra-thia-fulvalene (TTF), C(7)H(2)N(2)S(7), contains fused 1,2,5-thia-diazole and 1,3-dithiole rings and is a component mol-ecule for conducting organic solids. The TTF mol-ecule is disordered crystallographically over two orientations related by an inversion center, where each site is half-occupied. The mol-ecule is almost planar with an r.m.s. deviation of 0.096 Å. In the crystal structure, mol-ecules are linked by short inter-molecular S⋯S inter-actions [3.47 (2), 3.507 (8) and 3.517 (13) Å].

In the title compound, C(18)H(23)NOS(6), the dithiol-opyrrole ring is almost planar [r.m.s. deviation = 0.044 (3) Å] and makes a dihedral angle of 25.11 (7)° with the dithiole ring. In the crystal, pairs of neighboring mol-ecules are connected by weak inter-molecular C-H⋯O inter-actions. These dimers are further linked into a chain along [110] by C-H⋯O inter-actions.

The asymmetric unit of the title compound, C(19)H(19)NOS(6), contains two independent mol-ecules with different conformations of the ethyl groups. The dihedral angles between the pyrrole and benzene rings are 14.19 (14) and 16.29 (17)° in the two molecules. In the absence of short inter-molecular contacts, in the crystal, the mol-ecules are packed with their long axes parallel to [10].
