The First Dinuclear Nickel(II) Thiosulfate Obtained From Oxidation of Tri‐tert‐butoxysilanethiol. Contributions to the Chemistry of Silicon‐Sulfur Compounds No. 78^[1]

Abstract

The title complex, neutral {[Ni 2 (μ-S 2 O 3 ) 2 (C 7 H 9 N) 4 -H 2 O]C 7 H 8 } (1), presents a dinuclear structure with the thiosulfate group acting as a (S,O) chelate and simultaneously as a (S) bridge. The molecular structure was determined by X-ray crystallography. Complex 1 crystallizes as a hydrogen-bonded dimer with molecule of toluene solvent in the unit cell.

Synthesis of tetraphenylporphyrinate manganese(III) siloxides by silyl group transfer from silanethiols

“…Exposure of the [Mn II (TPP)] solution to air leads immediately to UV-vis absorbances consistent with oxidation back to Mn(III) porphyrinate species [44]. In concert with oxidation of the manganese center, the silyldisulfide is converted to a mixture of the corresponding silanol and the thiosulfate in similar fashion to that reported by Pladzyk and coworkers for the related tri-tert-butoxysilyldisulfide [34]. The in situ generated silanol then reacts with the Mn(III) porphyrinate to produce the corresponding Mn(III) siloxide complex (scheme 7).…”

3,5-Lutidine pentaaqua sulfate complexes of first-row transition metals: [M(3,5-lutidine)(H2O)5]SO4, with M = Mn, Co, Ni, and Zn

“…copper sulfate complex (IWAWEJ; Bowmaker et al, 2011), and a bis(3,5-lutidine) nickel thiosulfate dimer (BEMNIS; Pladzyk et al, 2012).…”

Bis(diisopropylammonium) thiosulfate and bis(tert-butylammonium) thiosulfate

“…We found that the hydrogen bonds in these adducts were of a robust charge-assisted N + -HÁ Á ÁS À type and because of the proton transfer they are better described as salts (Becker et al, 2004). We turned our attention to the thiosulfate anion because it can act as an S-donor ligand (Pladzyk et al, 2012) and, besides oxygen, one of its S atoms is able to serve as a hydrogen-bond acceptor.…”
