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 (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 elemental 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).

Mercury is a chemical element; it has symbol Hg and atomic number 80. It is also known as quicksilver and was formerly named hydrargyrum (/ h aɪ ˈ d r ɑːr dʒ ər ə m / hy-DRAR-jər-əm) from the Greek words hydor ' water ' and argyros ' silver ', from which its chemical symbol is derived. [9]
In contrast, an analysis reported in 1998 of a different "red mercury" sample concluded that this sample was a non-radioactive mixture of elemental mercury, water and mercury(II) iodide, which is a red colored chemical. [1] Similarly, another analysis of a sample recovered in Zagreb in November 2003 reported that this item contained only ...

Genuine vermilion pigment today comes mostly from China; it is a synthetic mercuric sulfide, labeled on paint tubes as PR-106 (Red Pigment 106). The synthetic pigment is of higher quality than vermilion made from ground cinnabar, which has many impurities. The pigment is very toxic, and should be used with great care. [16]
