%X Reaction of [(PPh2NSiMe3)(PPh2S)CSn:]2 (1) with
elemental sulfur in toluene afforded [{(μ-S)SnIVC(PPh2NSiMe3)(PPh2S)}3SnII(μ3-S)] (2) and [CH2(PPh2NSiMe3)(PPh2S)] (3). Compound 2 comprises a SnIIS moiety coordinated with the
SnIV and S atoms of a trimeric 2-stannathiomethendiide
{(PPh2NSiMe3)(PPh2S)CSn(μ-S)}3. Compound 2 has been characterized by NMR spectroscopy, 119Sn Mössbauer studies, X-ray crystallography, and
theoretical studies. 119Sn NMR spectroscopy and Mössbauer
studies show the presence of SnIV and SnII atoms
in 2. X-ray crystallography suggests that the SnIIS moiety does not have multiple bond character. Theoretical
studies illustrate that the Cmethanediide–Sn bonds
comprise a lone pair orbital on each Cmethanediide atom
and an C–Sn occupied σ orbital.
