The material described by MnCO3 is Calcite structured and crystallizes in the trigonal R3c space group. Mn(1) is bonded to six equivalent O(1) atoms to form corner-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles are 60°. C(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. O(1) is bonded in a trigonal planar geometry to two equivalent Mn(1) and one C(1) atom. is represented by the CIF file [CIF]
