Aggregation patterns in the crystal structures of organometallic Group XV 1,1-dithiolates: the influence of the Lewis acidity of the central atom, metal- and ligand-bound steric bulk, and coordination potential of the 1,1-dithiolate ligands upon supramolecular architecture

“…The dominant intermolecular interactions in this structure are of the type C-H … S. As illustrated in Fig. 7, these lead to a chain, 35,36 the supramolecular structure of PhAs[S 2 P(OiPr) 2 ] 2 features a S … S interaction of 3.580 (14) A between centrosymmetrically related S4 atoms, again at the margin of significance. There are three organoarsenic dithiophosphinate structures available in the literature (Table 2) and each of these features a bidentate diorgano ligand as seen previously in the structure of O(C 6 H 4 ) 2 As[S 2 CN(CH 2 ) 4 ], shown in Fig.…”

“…[1][2][3][4] Overviews of the supramolecular chemistry of Group XV compounds have shown that all of above-mentioned supramolecular synthons can occur. [5][6][7][8][9][10][11][12][13][14][15][16] The particular theme of this overview is to systematically survey the supramolecular association found in the organometallic structures of the Group XV elements containing 1,1-dithiolate ligands such as dithiocarbamate, xanthate, dithiophosphate, etc. (see Chart 1).…”

Structural variation in ethylenediamine and -diphosphine adducts of (2,6-Me2C6H3S)2Pb: a single crystal X-ray diffraction and 207Pb solid-state NMR spectroscopy study

“…Heavy p-block metals, such as Pb(II), are potentially diverse coordination centers for such systems. [7][8][9][10][11][12][13] For example, the large atomic radius of Pb(II) allows high coordination numbers for the element, while the number of possible bonding environments is augmented by the variable stereochemical activity of its valence lone pair. 11,[13][14][15][16] The preference for high coordination numbers typically manifests itself in the formation of polymeric species, as is observed in the solid-state structures of the Pb(II) thiolates [(RS) 2 Pb] 4 (R = C 6 H 5 , 4-MeC 6 H 4 , CH 2 ) [17][18][19][20] via extensive intermolecular Pb⋯S interactions.…”

Supramolecular associations in binary antimony(iii) dithiocarbamates: influence of ligand steric bulk, influence on coordination geometry, and competition with hydrogen-bonding

“…[1][2][3][4] Surveys of, and systematic studies on, antimony compounds have shown that all of abovementioned Sb … Y supramolecular synthons can occur. [5][6][7][8][9][10][11][12][13] In terms of crystal engineering, the question arises whether such synthons persist in series of closely related compounds and thereby, whether they can be exploited as a design element. Metal dithiocarbamates, including those of Group XV, continue to garner attraction owing to their diverse range of applications in agriculture, industry, medicine and nanotechnology (as synthetic precursors).…”
