The compound [Hg3S2CI2] has been obtained by solid-state reactions. It crystallises in the acentric space group R3 of the rhombohedral system with six formula units in a cell [a = b = 12.654(3), c = 7.753(4) Å, V = 1075.1(6) Å3, CI2Hg3S2, Mr = 736.79, Dc = 6.828 g cm−3, S = 0.987, μ(MoKα) = 65.308 mm−1, F(000) = 1836, R = 0.0631 and wR = 0.1443] and is characterised by a 3-D framework structure, which is composed of interconnected right-handed helices formed by tetrahedral Hg atoms. Optical absorption spectra reveal the presence of an optical bandgap of 2.51 eV and the composition Hg3S2CI2 is confirmed by semiquantitative microscope analysis.
