چکیده
The asymmetric unit of the title compound, C(9)H(4)S(7), contains two independent mol-ecules, in one of which the central five-membered ring is disordered over two orientations in a 0.924 (3):0.076 (3) ratio. The mol-ecular skeleton is almost planar: the average distance of the atoms from their mean plane is 0.128 (7) Å in the ordered mol-ecule, and 0.088 (5) and 0.123 (2) Å in the major and minor disorder components, respectively. The ordered and disordered mol-ecules form separate columns by stacking along the b axis. Adjacent columns inter-act via short S⋯S [3.33 (2), 3.434 (3), 3.444 (2), 3.503 (2), 3.519 (3) and 3.53 (4) Å] and S⋯H [2.814 (2), 2.87 (7), 2.92 (2), 2.9269 (18), 2.93 (2), 2.94 (2), 2.939 (2), 2.967 (2) and 2.974 (1) Å] contacts.

متن کامل[2.2]Paracyclophane derivatives containing tetrathiafulvalene moieties
The synthesis of [2.2]paracyclophane derivatives containing tetrathiafulvalene units has been accomplished by the coupling reaction of 4-([2.2]paracyclophan-4-yl)-1,3-dithiol-2-thione in the presence of trimethylphosphite. The 1,3-dithiol-2-thione derivative was in turn synthesized by the regioselective bromination of 4-acetyl[2.2]paracyclophane, then through the corresponding dithiocarbamates ...

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 mol-ecular framework of the title compound, C(11)H(6)I(2)OS(8), is almost planar [maximum deviation = 0.057 (5) Å] except for the two methyl-sulfanyl groups, which are twisted relative to the mol-ecular skeleton, with C-C-S-C torsion angles of 49.74 (22) and 82.91 (21)°. In the crystal, mol-ecules are stacked alternately in opposite orientations, forming a one-dimensional column along the b...
