The structure described by K2Mn2O3 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. Mn(1) is bonded to one O(1) and three equivalent O(2) atoms to form a mixture of corner and edge-sharing MnO4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent K(1) and two equivalent Mn(1) atoms to form corner-sharing OK4Mn2 octahedra. The corner-sharing octahedral tilt angles are 63°. In the second O site, O(2) is bonded in a 5-coordinate geometry to two equivalent K(1) and three equivalent Mn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
