The compound described by (MnO2)8N2 is Rutile-derived structured and crystallizes in the tetragonal I4/m space group. The structure consists of two ammonia atoms inside a MnO2 framework. In the MnO2 framework, Mn(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form a mixture of corner and edge-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Mn(1) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to three equivalent Mn(1) atoms. is represented by the CIF file [CIF]
