“…Previous studies using a small excess of ligand (2.1:1 ligand to metal ratio) produced a monomer and dimer without any 2 being detected. 50 Differences in relative spikelet intensities before and after crystallization are attributed to changes in the physical sample morphology (though it is noted that these spectra cannot be used for quantitative interpretation without careful calibration of known standards). In the case of 2, the spectra before and after are noticeably different, which we attribute to differences in the molecular conformation and different physical sample morphology instigated by the incorporation of ether, which occurs during the crystal growth (indicated by disordered ether molecules within the crystal structure of 2).…”

“…We therefore investigated the formation of mercury(II) di-isopropyldithiocarbamate complexes, which can exist in multiple structural forms. [48][49][50] We employed solid-and solution-state techniques to track the formation of monomeric, dimeric and polymeric mercury(II) di-isopropyldithiocarbamate complexes from the initial reaction between metal and ligand, to the isolation of individual crystals. Solid-state NMR ( 13 C and 199 Hg) spectroscopy and single crystal X-ray diffraction were definitive in demonstrating the structural differences.…”

A new polymeric mercury(II) di-isopropyldithiocarbamate complex was synthesized by the reaction of sodium di-isopropyldithiocarbamate with excess HgCl2 in water. The precise structure of the new compound was determined by single crystal X-ray diffraction. A similar reaction, using a stoichiometric excess of the ligand, yielded the known monomeric bis(di(isopropyl)dithiocarbamato)mercury(II) complex. The complexes could not be distinguished from each other by their solution phase NMR spectra nor their FTIR spectra. Solid state NMR spectroscopy ( 199 Hg and 13 C) provided unambiguous data and showed that the monomeric complex and polymeric complex do not interconvert in solution or during crystal growth.Thermogravimetric experiments revealed quite different thermal decomposition behaviour between the two compounds.

“…The capricious behaviour relating to coordination geometries, Hg-S bond lengths, and supramolecular association via Hg···S secondary bonding interactions is no better illustrated than for the pair of structures, mononuclear and square-planar Hg(S2CNEt2)2 (157) [149], which self-associates into a supramolecular chain via Hg·· · S contacts, Figure 14c, and binuclear {Hg(S2CNEt2)]2 (163) [149,153], Figure 15a; that is, the same compound can adopt either motif X or O, respectively. Similarly, strictly mononuclear Hg[S2CN(i-Pr)2]2 (142) [149], motif M, in one polymorph can also adopt binuclear motif O in another, as in 164 [154]. Figure 15b, has one chelating dithiocarbamate ligand and one bridging ligand, whereby one end chelates a mercury atom and bridges another via the pyridyl-nitrogen atom; this structure conforms to motif Q.…”

Abstract:The crystal chemistry of the zinc-triad binary 1,1-dithiolates, that is, compounds of xanthate [ − S 2 COR], dithiophosphate [ − S 2 P(OR) 2 ], and dithiocarbamate [ − S 2 CNR 2 ] ligands, is reviewed. Owing to a wide range of coordination modes that can be adopted by 1,1-dithiolate anions, such as monodentate, chelating, µ 2 -bridging, µ 3 -bridging, etc., there exists a rich diversity in supramolecular assemblies for these compounds, including examples of zero-, one-, and two-dimensional architectures. While there are similarities in structural motifs across the series of 1,1-dithiolate ligands, specific architectures are sometimes found, depending on the metal centre and/or on the 1,1-dithiolate ligand. Further, an influence of steric bulk upon supramolecular aggregation is apparent. Thus, bulky R groups generally preclude the close approach of molecules in order to reduce steric hindrance and therefore, lead to lower dimensional aggregation patterns. The ligating ability of the 1,1-dithiolate ligands also proves crucial in determining the extent of supramolecular aggregation, in particular for dithiocarbamate species where the relatively greater chelating ability of this ligand reduces the Lewis acidity of the zinc-triad element, which thereby reduces its ability to significantly expand its coordination number. Often, the functionalisation of the organic substituents in the 1,1-dithiolate ligands, for example, by incorporating pyridyl groups, can lead to different supramolecular association patterns. Herein, the diverse assemblies of supramolecular architectures are classified and compared. In all, 27 structurally distinct motifs have been identified.
