Low temperature activation of S8, Sered and α-Te with [CpBIGFe(CO)2] radicals

Abstract

The bulky dimeric iron complex, [Cp^BIGFe(CO)₂]₂, readily activates elemental chalcogens (S₈, Se_red and α-Te) under mild conditions at room temperature. Six compounds containing Q₂²⁻ ligands (Q = S, Se) and a Te²⁻ ligand, respectively, were isolated and completely characterized, including by X-ray diffraction techniques.
