The compound described by Mn3O4 crystallizes in the orthorhombic Pbcm space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a see-saw-like geometry to two equivalent O(2) and two equivalent O(3) atoms. In the second Mn site, Mn(2) is bonded to one O(2), two equivalent O(1), and three equivalent O(3) atoms to form a mixture of distorted corner and edge-sharing MnO6 octahedra. The corner-sharing octahedra are not tilted. There are three inequivalent O sites. In the first O site, O(1) is bonded in a square co-planar geometry to four equivalent Mn(2) atoms. In the second O site, O(2) is bonded in a distorted see-saw-like geometry to two equivalent Mn(1) and two equivalent Mn(2) atoms. In the third O site, O(3) is bonded to one Mn(1) and three equivalent Mn(2) atoms to form a mixture of distorted corner and edge-sharing OMn4 trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
