Abstract: The structure of the title compound, [Mn₆(C₄H₉O₂)₁₀O₂(C₄H₁₀O₂)₄], has been redetermined at 100 K. The improved precision of the structure determination allowed the determination of the positions of the Mn^III atoms in the Mn₆O₂ core. The Mn^IIIMn^III distance of 2.744 (3) Å is significantly shorter than the remaining Mn^IIMn^III distances [3.106 (3)-3.137 (3) Å].
