Abstract

The synthesis, spectral characteristics -IR and NMR-, elemental analysis and X-ray crystal structure of phosphorothioic triamide SP-NC5H10-3 -1- and its dinuclear mercury-II- complex [Hg2-μ-Cl-2-Cl-2{SP-NC5H10-3}2] -2- were investigated. A survey using the Cambridge Structural Database -CSD, version 5.38, May 2017- shows structures of coordination compounds of Au, Ag, Cd, Cu, Li, Mo, Ni, Pd, Te, Ti, Zn, and Zr with sulfur-donor SP-N-3-based ligands; the complex 2 is the first example of a mercury complex with the SP-N-3-based ligand studied by X-ray crystallography. Valence bond calculation was performed for the Hg–S bond in 2 and compared with the Hg–O bond in the only structure with a Cl2Hg–OP-N-3 structural motive in the CSD. The calculation confirms a more covalent nature of the Hg–S bond with respect to the Hg–O bond made by the EP-N-3-based ligands -E = S, O-. The supramolecular structures based on C–H···S = P contacts in 1 and C–H···S═P and C–H···Cl–Hg assemblies in 2 are discussed.
