Reactivity of a Tin(II) (Iminophosphinoyl)(thiophosphinoyl)methanediide Complex Toward Sulfur: Synthesis and 119 Sn Mössbauer Spectroscopic Studies of [{(μ-S)SnC(PPh 2 ═NSiMe 3 )(PPh 2 ═S)} 3 Sn(μ 3 -S)]. Inorganic Chemistry, 51(7), 3996-4001. | Series/Report no.: | Inorganic chemistry | Abstract: | 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. | URI: | https://hdl.handle.net/10356/96723 http://hdl.handle.net/10220/11593 |
