The material structure described by MnOOH crystallizes in the monoclinic Cm space group. Mn(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form distorted edge-sharing MnO6 octahedra. H(1) is bonded in a linear geometry to one O(1) and one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to three equivalent Mn(1) and one H(1) atom. In the second O site, O(2) is bonded to three equivalent Mn(1) and one H(1) atom to form distorted corner-sharing OMn3H tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
