Diorganotin 1,3-dithiole-2-thione-4,5-dithiolate compounds, R2Sn(dmit): the crystal structure of MePhSn(dmit)

4,5-Bis[(triorganotin)thiolato]-1,3-dithiole-2-thione, (R3Sn)2(dmit), 4,5-bis[(triorganotin)thiolato]-1,3-dithiole-2-one, (R3Sn)2(dmio), compounds: Crystal structures of (cyclohexyl3Sn)2(dmio), (Ph3Sn)2(dmit) and (Ph3Sn)2(dmio)

“…When such strong intermolecular Sn-O and Sn-S interactions occur, the d 119 Sn differences are considerably greater, e.g., d 119 Sn values for polymeric Ph 2 Sn(dmio)/Ph 2 Sn-(dmit) the differences are ca. À237/À25 ppm, a difference of over 200 ppm [10,14]. This larger difference reflects the additional bonding to tin of the different carbonyl and thione chalcogen atoms.…”

“…While generally less frequently studied, emphasis on main group dmit complexes has been concentrated on structure determinations, with tin compounds being in the vanguard of these studies. Structures of various tin-dmit compounds have been reported, including those of [Q] 2 [Sn-(dmit) 3 ] (Q = monovalent cation) [4,5], [Q] 2 [X 2 Sn(dmit) 2 ] (X = Br or I) [6], [Q][RSn(dmit) 2 ] [7,8], R 2 Sn(dmit) [7,9,10] and [Q][R 2 SnX(dmit) [8,11] (R = alkyl or aryl). In all these tin compounds, the dmit ligand is acting as a chelating group.…”

“…O monômero é tetraédrico, como mostra a figura 6, mas sua cela unitária evidencia a presença de associação intermolecular, em que as moléculas se unem principalmente por ligações Sn-S(tiona), dando a cada unidade de Sn uma geometria BPT distorcida 31 34,35 . A figura 8 mostra um exemplo do primeiro tipo e dois do segundo [33][34][35] .…”

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

“…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).…”
