MnCO3 is Calcite-like structured and crystallizes in the triclinic P-1 space group. Mn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form a mixture of distorted corner and edge-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles are 61°. C(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent Mn(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Mn(1) and one C(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent Mn(1) and one C(1) atom.
