The compound described by MgMn2(HO2)2 crystallizes in the monoclinic Pm space group. Mg(1) is bonded in a 5-coordinate geometry to one H(1), one O(1), one O(2), and two equivalent O(3) atoms. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 5-coordinate geometry to one O(2), two equivalent O(3), and two equivalent O(4) atoms. In the second Mn site, Mn(2) is bonded to one O(4), two equivalent O(1), and two equivalent O(2) atoms to form distorted edge-sharing MnO5 trigonal bipyramids. 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(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one Mg(1), two equivalent Mn(2), and one H(1) atom. In the second O site, O(2) is bonded to one Mg(1), one Mn(1), and two equivalent Mn(2) atoms to form corner-sharing OMgMn3 tetrahedra. In the third O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Mg(1) and two equivalent Mn(1) atoms. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Mn(2), two equivalent Mn(1), and one H(2) atom. is represented by the CIF file [CIF]
