Bis(tetraethylammonium) octabromotrimercurate(II), (Et₄N)₂[Hg₃Br₈]

P. Nockemann and G. Meyer

Abstract: The structure of (Et₄N)₂[Hg₃Br₈] contains isolated dinuclear [Hg₂Br₆]^2- anions and neutral HgBr₂ molecules. Charge balance is achieved by ordered [Et₄N]⁺ cations. The formula may therefore be written as (Et₄N)₂[Hg₂Br₆][HgBr₂]. The N atoms of the (Et₄N)⁺ ions lie on a axis along [001] and, whereas one of the mercury(II) ions is placed on a mirror plane perpendicular to the c axis, the second one is located on a special position of site symmetry 2/m.
