Supramolecular aggregation featuring Hg⋯S secondary-bonding interactions in crystals of mercury(ii) species augmented by computational chemistry calculations

A CSD survey reveals the presence of Hg⋯S interactions within zero-, one- and two-dimensional aggregation patterns in non-organomercury crystals. Theory confirms the stabilising nature of σ-/π-holes or positive belts formed at the mercury atom.
