บทคัดย่อ/คำอธิบาย :

Reaction of [(PPh2═NSiMe3)(PPh2═S)CSn:]2 (1) with elemental sulfur in toluene afforded [{(μ-S)tiebar above startSnIVC(PPh2═NSiMe3)(PPh2═S)}3SnII(μ3-Stiebar above end)] (2) and [CH2(PPh2═NSiMe3)(PPh2═S)] (3). Compound 2 comprises a SnIIS moiety coordinated with the SnIV and S atoms of a trimeric 2-stannathiomethendiide {(PPh2═NSiMe3)(PPh2═S)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.
