Bis(tetraethylammonium) decachloro- tetramercurate(II), (Et₄N)₂[Hg₄Cl₁₀]

P. Nockemann and G. Meyer

Abstract: The structure of (Et₄N)₂[Hg₄Cl₁₀] contains dinuclear [Hg₂Cl₆]^2- anions and HgCl₂ molecules, with definite interactions so that the anion can also be formulated as [Hg₄Cl₁₀]^2-. Alternatively the compound can be written as (Et₄N)₂[Hg₂Cl₆][HgCl₂]₂. Charge balance is achieved by ordered [Et₄N]⁺ cations. An inversion centre is situated at the centre of the [Hg₂Cl₆]^2- anions.
