Mn2O5 crystallizes in the orthorhombic Pbam space group. Mn(1) is bonded to one O(3), two equivalent O(1), and two equivalent O(2) atoms to form distorted corner-sharing MnO5 trigonal bipyramids. There are three inequivalent O sites. In the first O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent Mn(1) atoms. In the second O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent Mn(1) atoms. In the third O site, O(3) is bonded in a linear geometry to two equivalent Mn(1) atoms.
Mn2O5 crystallizes in the orthorhombic Pbam space group. Mn(1) is bonded to one O(3), two equivalent O(1), and two equivalent O(2) atoms to form distorted corner-sharing MnO5 trigonal bipyramids. The Mn(1)-O(3) bond length is 1.83 Å. Both Mn(1)-O(1) bond lengths are 1.85 Å. There is one shorter (1.77 Å) and one longer (1.91 Å) Mn(1)-O(2) bond length. There are three inequivalent O sites. In the first O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent Mn(1) atoms. In the second O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent Mn(1) atoms.
