title: 5-Isopropyl-idene-1,3-dithiolo[4,5-d][1,3]dithiole-2-thione.
abstract: The title compound, C(7)H(6)S(5), contains a 5-yl-idene-1,3-dithiolo[4,5-d][1,3]dithiole-2-thione framework, which is an important synthetic precursor of multi-dimensional organic superconductors and conductors. The mol-ecular framework is planar with an r.m.s. deviation of 0.012 Å for the non-H atoms. In the crystal structure, mol-ecules are linked by short inter-molecular S⋯S inter-actions [3.501 (5) and 3.581 (4) Å], constructing a zigzag mol-ecular tape network along the c axis.
