As the mercury cell as used in the chlor-alkali industry (Castner–Kellner process) is being phased out over concerns over mercury emissions, the metallic mercury from these setups is converted into mercury sulfide for underground storage. With a band gap of 2.1 eV and its stability, it is possible to be used as photoelectrochemical cell. [8]
Mercury(II) sulfide, HgS, adopts the cinnabar structure described, and one additional structure, i.e. it is dimorphous. [16] Cinnabar is the more stable form, and is a structure akin to that of HgO : each Hg center has two short Hg−S bonds (each 2.36 Å ), and four longer Hg···S contacts (with 3.10, 3.10, 3.30 and 3.30 Å separations).
Mercury(I) sulfide or mercurous sulfide is a hypothetical chemical compound of mercury and sulfur, with chemical formula Hg 2 S.Its existence has been disputed; it may be stable below 0 °C or in suitable environments, but is unstable at room temperature, decomposing into metallic mercury and mercury(II) sulfide (mercuric sulfide, cinnabar).

7.7–7.8: References [2] [3] [4] Metacinnabar is the cubic form of mercury sulfide (HgS). It is the high temperature form and trimorphous with cinnabar (trigonal ...
Vermilion (sometimes vermillion) [1] is a color family and pigment most often used between antiquity and the 19th century from the powdered mineral cinnabar (a form of mercury sulfide). It is synonymous with red orange , which often takes a modern form, but is 11% brighter (at full brightness).
Montgomery, who became a stockholder in the X.L.C.R. [8] (pronounced "excelsior") mine, is the only known source of the often-repeated tale of Seth Dunham and L.D. Jones discovering cinnabar in a road cut of the Barryessa–Lower Lake Road (now Morgan Valley Road) [8] in what became known as the Knoxville mining district, about a dozen miles ...
