Mercury sulfide, or mercury(II) sulfide is a chemical compound composed of the chemical elements mercury and sulfur. It is represented by the chemical formula HgS. It is virtually insoluble in water.
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
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).
Metacinnabar is the cubic form of mercury sulfide (HgS). It is the high temperature form and trimorphous with cinnabar (trigonal structure) and the higher temperature hypercinnabar (hexagonal structure).
Sulfide (also sulphide in British English) [2] is an inorganic anion of sulfur with the chemical formula S 2− or a compound containing one or more S 2− ions. Solutions of sulfide salts are corrosive. Sulfide also refers to large families of inorganic and organic compounds, e.g. lead sulfide and dimethyl sulfide.
Mix mercury with sulfur to form aethiopes mineralis, a black compound of mercury sulfide. Heat this in a flask (the compound vaporizes and recondenses in the top of the flask). Break the flask. Collect the vermilion and grind it. When first created, the material is almost black. As it is ground, the red color appears.
Mercury(I) sulfate, commonly called mercurous sulphate or mercurous sulfate is the chemical compound Hg 2 SO 4. [3] Mercury(I) sulfate is a metallic compound that is a white, pale yellow or beige powder. [ 4 ]
Corderoite is an extremely rare mercury sulfide chloride mineral with formula Hg 3 S 2 Cl 2. It crystallizes in the isometric crystal system. It is soft, 1.5 to 2 on the Mohs scale, and varies in color from light gray to black and rarely pink or yellow. It was first described in 1974 for occurrences in the McDermitt Mercury mine in Humboldt ...
