Mercuric amidochloride is an inorganic compound with the formula Hg(NH2)Cl.
Preparation and properties
It arises from the reaction of mercury(II) chloride and ammonia (Calomel reaction), where the resulting mercuric amidochloride is highly insoluble.
- HgCl2 + 2 NH3 → HgCl(NH2) + [NH4]Cl
It forms white crystals in the shape of small prisms, which have earthy metallic taste.[1]It consists of a zig-zag 1-dimensional polymer (HgNH2)n with chloride counterions.[2][3]
It is stable in
This substance is a deadly poison. If improperly handled, may cause dangerous environmental pollution, in
Addition of base converts it into "Millon's base" (named after Eugène Millon), which has the formula Hg2(OH)N·xH2O. A variety of related amido and nitrido materials with chloride, bromide, and hydroxide are known.[4]
