Materials Data on TaHgS2 by Materials Project
HgTaS2 is H-Phase-like structured and crystallizes in the trigonal R-3m space group. The structure is two-dimensional and consists of three hydrargyrum molecules and three TaS2 sheets oriented in the (0, 0, 1) direction. In each TaS2 sheet, Ta3+ is bonded to six equivalent S2- atoms to form edge-sharing TaS6 octahedra. All Ta–S bond lengths are 2.48 Å. S2- is bonded in a distorted T-shaped geometry to three equivalent Ta3+ atoms.
