The structure described by Co2Mn3O8 crystallizes in the orthorhombic Pmn2_1 space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form MnO6 octahedra that share corners with two equivalent Co(1)O6 octahedra, corners with three equivalent Co(2)O4 tetrahedra,  an edgeedge with one Co(1)O6 octahedra, edges with two equivalent Mn(1)O6 octahedra, and edges with two equivalent Mn(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 50-55°. In the second Mn site, Mn(2) is bonded to one O(4), one O(5), two equivalent O(1), and two equivalent O(2) atoms to form MnO6 octahedra that share corners with three equivalent Co(1)O6 octahedra, corners with three equivalent Co(2)O4 tetrahedra,  an edgeedge with one Co(1)O6 octahedra, and edges with four equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 11-48°. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to one O(3), one O(5), two equivalent O(1), and two equivalent O(2) atoms to form CoO6 octahedra that share corners with three equivalent Mn(2)O6 octahedra, corners with four equivalent Mn(1)O6 octahedra, corners with two equivalent Co(2)O4 tetrahedra,  an edgeedge with one Mn(2)O6 octahedra, and edges with two equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 11-55°. In the second Co site, Co(2) is bonded to one O(4), one O(6), and two equivalent O(2) atoms to form CoO4 tetrahedra that share corners with two equivalent Co(1)O6 octahedra, corners with three equivalent Mn(2)O6 octahedra, and corners with six equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 59-65°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Mn(1), one Mn(2), and one Co(1) atom. In the second O site, O(2) is bonded to one Mn(1), one Mn(2), one Co(1), and one Co(2) atom to form OMn2Co2 tetrahedra that share  a cornercorner with one O(2)Mn2Co2 tetrahedra,  a cornercorner with one O(4)Mn3Co tetrahedra,  an edgeedge with one O(2)Mn2Co2 tetrahedra, and  an edgeedge with one O(4)Mn3Co tetrahedra. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent Mn(1) and one Co(1) atom. In the fourth O site, O(4) is bonded to one Mn(2), two equivalent Mn(1), and one Co(2) atom to form a mixture of distorted corner and edge-sharing OMn3Co tetrahedra. In the fifth O site, O(5) is bonded in a distorted rectangular see-saw-like geometry to one Mn(2), two equivalent Mn(1), and one Co(1) atom. In the sixth O site, O(6) is bonded in a distorted trigonal planar geometry to two equivalent Mn(1) and one Co(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
