Mn2Zn2O5 crystallizes in the orthorhombic Pbam space group. Mn(1) is bonded to one O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted corner-sharing MnO5 trigonal bipyramids. Zn(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to two equivalent Mn(1) and four equivalent Zn(1) atoms. In the second O site, O(2) is bonded to two equivalent Mn(1) and two equivalent Zn(1) atoms to form a mixture of corner and edge-sharing OMn2Zn2 tetrahedra. In the third O site, O(3) is bonded to two equivalent Mn(1) and two equivalent Zn(1) atoms to form a mixture of distorted corner and edge-sharing OMn2Zn2 trigonal pyramids.
Mn2Zn2O5 crystallizes in the orthorhombic Pbam space group. Mn(1) is bonded to one O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted corner-sharing MnO5 trigonal bipyramids. The Mn(1)-O(1) bond length is 2.01 Å. Both Mn(1)-O(2) bond lengths are 2.08 Å. Both Mn(1)-O(3) bond lengths are 1.88 Å. Zn(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Both Zn(1)-O(1) bond lengths are 2.56 Å.
