The compound described by MnCO3 crystallizes in the monoclinic Cc space group. Mn(1) is bonded in a 5-coordinate geometry to one O(2), two equivalent O(1), and two equivalent O(3) atoms. 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 distorted trigonal planar geometry to two equivalent Mn(1) and one C(1) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to one Mn(1) and one C(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Mn(1) and one C(1) atom. is represented by the CIF file [CIF]
