AI Article Synopsis
- The reaction of a compound containing tin and sulfur with elemental sulfur in toluene results in two new complexes: one is a trimeric structure involving both Sn(IV) and Sn(II), while the other is a substituted derivative.
- Compound 2 includes a unique Sn(II)S group that features in a trimeric arrangement with sulfur and tin, showcasing distinct bonding characteristics.
- Characterization techniques such as NMR spectroscopy, Mössbauer studies, X-ray crystallography, and theoretical analysis indicate the presence of both oxidation states of tin and reveal insights into the bonding nature within the compounds.
Article Abstract
Reaction of [(PPh(2)═NSiMe(3))(PPh(2)═S)CSn:](2) (1) with elemental sulfur in toluene afforded [{(μ-S)Sn(IV)C(PPh(2)═NSiMe(3))(PPh(2)═S)}(3)Sn(II)(μ(3)-S)] (2) and [CH(2)(PPh(2)═NSiMe(3))(PPh(2)═S)] (3). Compound 2 comprises a Sn(II)S moiety coordinated with the Sn(IV) and S atoms of a trimeric 2-stannathiomethendiide {(PPh(2)═NSiMe(3))(PPh(2)═S)CSn(μ-S)}(3). Compound 2 has been characterized by NMR spectroscopy, (119)Sn Mössbauer studies, X-ray crystallography, and theoretical studies. (119)Sn NMR spectroscopy and Mössbauer studies show the presence of Sn(IV) and Sn(II) atoms in 2. X-ray crystallography suggests that the Sn(II)S moiety does not have multiple bond character. Theoretical studies illustrate that the C(methanediide)-Sn bonds comprise a lone pair orbital on each C(methanediide) atom and an C-Sn occupied σ orbital.
