Özet

The structure of the title compound, [Mn-6(C4H9O2)(10)O-2(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(III)cMn(III) distance of 2.744 (3) angstrom is significantly shorter than the remaining Mn(II)cMn(III) distances [3.106 (3)-3.137 (3) angstrom].
