Mn2ZnO5 crystallizes in the orthorhombic Cmcm space group. Mn(1) is bonded to one O(1), one O(3), and three equivalent O(2) atoms to form distorted MnO5 trigonal bipyramids that share corners with two equivalent Zn(1)O6 tetrahedra, corners with three equivalent Mn(1)O5 trigonal bipyramids, edges with two equivalent Zn(1)O6 tetrahedra, and edges with two equivalent Mn(1)O5 trigonal bipyramids. Zn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted ZnO6 tetrahedra that share corners with two equivalent Zn(1)O6 tetrahedra, corners with four equivalent Mn(1)O5 trigonal bipyramids, and edges with four equivalent Mn(1)O5 trigonal bipyramids. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Mn(1) and two equivalent Zn(1) atoms to form corner-sharing OMn2Zn2 tetrahedra. In the second O site, O(2) is bonded in a 3-coordinate geometry to three equivalent Mn(1) and one Zn(1) atom. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Mn(1) and one Zn(1) atom.

The Mn(1)-O(1) bond length is 1.94 Å. The Mn(1)-O(3) bond length is 1.74 Å. There are two shorter (1.91 Å) and one longer (2.02 Å) Mn(1)-O(2) bond length. Zn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted ZnO6 tetrahedra that share corners with two equivalent Zn(1)O6 tetrahedra, corners with four equivalent Mn(1)O5 trigonal bipyramids, and edges with four equivalent Mn(1)O5 trigonal bipyramids. Both Zn(1)-O(1) bond lengths are 2.15 Å. Both Zn(1)-O(2) bond lengths are 2.52 Å. Both Zn(1)-O(3) bond lengths are 1.94 Å. There are three inequivalent O sites.
