The structure described by ZnMn2O4 crystallizes in the orthorhombic Pbcm space group. Mn(1) is bonded to one O(3), two equivalent O(2), and three equivalent O(1) atoms to form a mixture of corner and edge-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles range from 9-55°. Zn(1) is bonded in a 6-coordinate geometry to two equivalent O(3) and four equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Mn(1) and two equivalent Zn(1) atoms to form distorted OMn3Zn2 trigonal bipyramids that share corners with five equivalent O(3)Mn2Zn2 tetrahedra, corners with two equivalent O(1)Mn3Zn2 trigonal bipyramids,  an edgeedge with one O(3)Mn2Zn2 tetrahedra, and edges with five equivalent O(1)Mn3Zn2 trigonal bipyramids. In the second O site, O(2) is bonded in a distorted rectangular see-saw-like geometry to four equivalent Mn(1) atoms. In the third O site, O(3) is bonded to two equivalent Mn(1) and two equivalent Zn(1) atoms to form OMn2Zn2 tetrahedra that share corners with two equivalent O(3)Mn2Zn2 tetrahedra, corners with ten equivalent O(1)Mn3Zn2 trigonal bipyramids, and edges with two equivalent O(1)Mn3Zn2 trigonal bipyramids. is represented by the CIF file [CIF]
