Supramolecular association in organomercury(ii) 1,1-dithiolates. Complementarity between Hg⋯S and hydrogen bonding interactions in organomercury(ii) 2-amino-cyclopent-1-ene-1-carbodithioates

Abstract

A survey of the supramolecular associations operating in the crystal structures of organomercury 1,1-dithiolates shows that owing to the presence of Hg⋯S interactions, dimeric, 1-, 2- and 3-dimensional architectures are generated. Introducing hydrogen-bonding functionality into the 1,1-dithiolate ligand allows for the formation of both intra- and intermolecular hydrogen bonds as well as Hg⋯S interactions, so that 2- and 3-dimensional architectures are formed that are distinct for each of the two polymorphic forms of MeHg(S₂CC₅H₆NH₂-2) and for PhHg(S₂CC₅H₆NH₂-2).
