The crystal structure described by MgMn4(HO2)4 crystallizes in the triclinic P-1 space group. Mg(1) is bonded to two equivalent H(1), two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form distorted MgH2O6 hexagonal bipyramids that share edges with four equivalent Mn(2)O6 octahedra. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 6-coordinate geometry to one O(2), one O(4), two equivalent O(1), and two equivalent O(3) atoms. In the second Mn site, Mn(2) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form distorted MnO6 octahedra that share edges with two equivalent Mg(1)H2O6 hexagonal bipyramids and edges with two equivalent Mn(2)O6 octahedra. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one Mg(1) and one O(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(2) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Mg(1), one Mn(2), two equivalent Mn(1), and one H(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Mn(1), two equivalent Mn(2), and one H(2) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Mg(1), one Mn(2), and two equivalent Mn(1) atoms. In the fourth O site, O(4) is bonded in a rectangular see-saw-like geometry to one Mg(1), one Mn(1), and two equivalent Mn(2) atoms. is represented by the CIF file [CIF]
