title: catena-Poly[[4',5'-bis-(methyl-sulfan-yl)-4,5-ethyl-enedithio-tetra-thio-fulvalene] [[dichloridomercurate(II)]-μ-dichlorido]].
abstract: The title compound, {(C(10)H(10)S(8))[HgCl(3)]}(n), is a sulfur-rich charge-transfer compound in which C(10)H(10)S(8) (+) cations and HgCl(3) anions are assembled by S⋯S [3.371 (5)-3.588 (5) Å] and S⋯Cl [2.833 (4)-3.488 (4) Å] contacts, and by weak inter-molecular C-H⋯Cl hydrogen bonds, forming a two-dimensional wave-like structure. The two C atoms of the -CH(2)-CH(2)- group in one of the cations are disordered over two sites with relative occupancies of 0.83 (2) and 0.17 (2).
