Diphenyl(2-thioxo-1,3-dithiole-4,5-dithiolato-S,S′)plumbane at 295 K and diphenyl(2-thioxo-1,3-dithiole-4,5-dithiolato-S,S′)stannane at 150 K

Abstract

Molecules of diphenyl(2-thioxo-1,3-dithiole-4,5-dithiolato-S,S')plumbane, [Pb(C3S5)(C6H5)2], are linked into sheets via two intermolecular Pb...S(thione) interactions of 3.322 (4) and 3.827 (4) A; the Pb centre has a distorted octahedral geometry. In contrast, molecules of diphenyl(2-thioxo-1,3-dithiole-4,5-dithiolato-S,S')stannane, [Sn(C3S5)(C6H5)2], are linked into chains via a single intermolecular Sn--S(thione) interaction of 2.8174 (9) A; the Sn centre has a distorted trigonal-bipyramidal geometry.

Synthesis of bis(tert-butyl)(2-thioxo-1,3-dithiole-4,5-dithiolato)stannane, But2Sn(dmit), and bis(tert-butyl)(2-oxo-1,3-dithiole-4,5-dithiolato)stannane, But2Sn(dmio): Crystal structures, at 120K, of polymeric But2Sn(dmit), and two polymorphs of But2Sn(dmio), a polymer and a cyclic tetramer

“…These Sn-S intermolecular interactions lead to the formation of layers of molecules. For the other independent molecule of monoclinic-Et 2 Sn(dmit), only one intermolecular Sn-S separation, 3.555(2) Å, is clearly within the van der Waals sum: the next, at 3.927(2) Å, is only slightly less than this limit. At the very most, this indicates a very weak interaction.…”

“…The Sn-S intermolecular bond lengths in R 2 Sn(dmit) compounds, having a single Sn-S intermolecular interaction per molecule, are 2.8174(9) Å, in Ph 2 Sn(dmit) [3], 3.139(1) Å, in PhMeSn(dmit) [1], 2.960(2) Å, in Mol. A, and 3.001(2) Å, in Mol.…”

“…As shown in Table 1, the strength and number of the Sn-S intermolecular interactions vary. Single Sn-S intermolecular interactions per molecule have been found for Ph 2 Sn(dmit) [intermolecular Sn-S = 2.8174(9) Å] [3], PhMeSn(dmit) [3.139(1) Å] [1], Me 2 Sn(dmit) [2.960(2) Å, in Mol. A, and 3.001(2) Å, in Mol.…”

“…We have previously reported the preparations and structures of the 1,2-dithiolato compounds, diorgano(2-thioxo-1,3-dithiole-4,5-dithiolato)stannanes, R 2 Sn(dmit) [1][2][3][4][5], and diorgano(2-oxo-1,3-dithiole-4,5-dithiolato)stannanes, R 2 Sn(dmio) compounds [6,7], while others have reported the uses of R 2 Sn(dmit) as dmit transfer agents [8] (Fig. 1).…”
