Generation of maghemite nanocrystals from iron–sulfur centres

Abstract

Electron beam induced generation of maghemite nanocrystals from polymer-encapsulated iron–sulfur centres.

Cu(iii)–bis-thiolato complex forms an unusual mono-thiolato Cu(iii)–peroxido adduct

“…11,12 The synthesis of [bis(toluene-3,4-dithiolato)copper(III)][NEt 3 H] (NEt 3 HÁ1) was based on reported procedures for similar ligand systems. 13,14 In the present case it was carried out in air, with O 2 present as a likely electron acceptor. 13,14 The formation of 1 was confirmed by 1 X-ray photoelectron spectroscopy (XPS) analysis of the Cu 2p 3/2 region further confirmed the Cu(III) oxidation state, as the feature at 934.9 eV falls within the previously established range of 934-935 eV for the Cu 2p 3/2 feature of Cu(III) complexes ( Fig.…”
