Supramolecular Self-Organization in Mercury(II) Dicyclopentyldithiophosphate Polynuclear Complex

Abstract

In the monomeric unit [Hg(μ-S₂P(OCp)₂) (S₂P(OCp)₂)] (Cp = cyclopentyl) moiety, the one dithiophosphate ligand acts as a chelating ligand and the other one acts as a bridging ligand by their sulfur atoms. The monomeric units arrange in order to give rise to an infinite polymeric structure along the direction of the b axis by the two-fold screw axis. The compound displays a supramolecular self-organization in the solid state through the additional Hg····S (3.516 Å) secondary interactions with formation of chain-like polymeric arrays. Also, there are some weak intra- and intermolecular hydrogen bonds between some of the hydrogen atoms of Cp and S atoms. The intermolecular hydrogen bonds form infinite polymeric chains that lie along the b axis, to each other, and along the c axis to contribute to the supramolecular association.
