Abstract:
The compound [Hg 3 S 2 CI 2 ] has been obtained by solid-state reactions. It crystallises in the acentric space group R 3 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) Å 3 , CI 2 Hg 3 S 2 , M r = 736.79, D c = 6.828 g cm −3 , S = 0.987, μ(Mo Kα) = 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 Hg 3 S 2 CI 2 is confirmed by semiquantitative microscope analysis.
