The material described by MnO2 is Hydrophilite structured and crystallizes in the orthorhombic Pnnm space group. Mn(1) is bonded to six equivalent O(1) atoms to form a mixture of corner and edge-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles are 50°. O(1) is bonded in a trigonal planar geometry to three equivalent Mn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
