Supersized mercury: Adducts with polymeric (left) or discrete supersandwich structures (right) form from mixtures of the trinuclear mercury complex [(o-C6F4Hg)3] (A) with the triple-decker complex [(CpMo)2(μ-η66-P6)] (B) in the solid state. This arrangement arises from P⋅⋅⋅Hg interactions between opposing atoms of the P6 units and the Hg3 units (see picture; P purple, Hg orange, F green, Mo red, C gray).
