Diphenylmercury is a colourless, crystalline[2] organomercury compound with the chemical formula C12H10Hg. It can be synthesised by the reaction of a 2:1 molar ratio of mercury(II) chloride and methyltriphenyltin in ethanol.[2] As with almost all organomercury compounds, the coordination geometry at mercury is linear.[2]

Preparation

Commercially available, the synthesis of this compound has been variously described in the literature. Diphenylmercury may be prepared by the reaction of phenylmercury acetate with benzene in the presence of sodium stannite,[3] by the reaction of mercury halides with phenylmagnesium bromide,[4] and the reaction of bromobenzene with sodium amalgam.[5]
