Mercury(I) hydride is a chemical compound with the chemical formula HgH. Mercury(I) hydride is a metal hydride composed of mercury and hydrogen. It is not well-characterised or well-known, and is thermodynamically unstable with repect to the loss of the hydrogen atom.
Mercury(I) hydride is an unstable gas and is the heaviest group 12 monohydride. Furthermore, mercury(I) hydride has a linear (C∞v) structure.
The Hg-H bond is very weak and therefore the compound has only been detected in matrix isolation at temperatures up to 6 K. The dihydride, HgH2, has also been detected this way.
