Supramolecular Association via Hg···S Secondary-Bonding Interactions in Crystals of Organomercury(II) Species: A Survey of the Cambridge Structure Database

The Cambridge Structural Database has been surveyed for crystals featuring organo-Hg···S secondary-bonding interactions within supramolecular aggregates. Nearly 50% of where Hg···S could potentially form, featured contacts zero- or one-dimensional assemblies with only a few examples two-dimensional arrays interactions. This high propensity contact formation reflects the inherent thiophilic nature mercury but also relatively open access to owing linear C–Hg–S coordination geometries, prevalence close intramolecular Hg···S, Hg···O and Hg···N notwithstanding.
