Preparation and structural characterisation of [NEt4]2[Mn2(SCH2CH2S)4], a stable manganese(III)–thiolate dimer
Abstract
Controlled air oxidation of [Mn(edt)2]2–(edt = ethane-1,2-dithiolate) in ethanolic solution yield deep green [Mn2(edt)4]2– which has been structurally characterized as its NEt4+ salt; the anion consists of a bis-thiolate-bridged manganese(III) dimer, establishes the existence of a stable manganese(III)–thiolate bond, and supports the possible occurrence of this linkage in manganese(III)-containing biological systems.
