Two [Mn 4 (μ 3 ‐O) 2 ] moieties with butterfly structure , which are coupled via a common Mn atom, are present in the cation of the title compound (structure with coordinated N () and O atoms () shown below). The complex cation, which contains six Mn III centers and one Mn II center, is formed in the reaction of manganese(II) acetate and triethylenetetramine in methanol. During the reaction a part of the tetramine ligand is cleaved oxidatively with formation of diethylenetriamine.
