The structure described by MnOOH crystallizes in the orthorhombic Pmn2_1 space group. Mn(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form a mixture of distorted corner and edge-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles range from 54-55°. 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 distorted single-bond 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 CIF card [CIF]
