Controlled air oxidation of [Mn(edt)2]2â(edt = ethane-1,2-dithiolate) in ethanolic solution yield deep green [Mn2(edt)4]2â 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)âthiolate bond, and supports the possible occurrence of this linkage in manganese(III)-containing biological systems.
                                    在
乙醇溶液中对[Mn(edt)2]2â(edt = 
乙烷-1,2-二
硫酸盐)进行受控空气氧化,得到了深绿色的[Mn2(edt)4]2â,其结构特征为NEt4+盐;阴离子由双
硫代酸连接的
锰(III)二聚体组成,确定了稳定的
锰(III)-
硫代酸键的存在,并支持在含
锰(III)的
生物系统中可能存在这种连接。
