The compound described by Mn(CO3)2 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in an octahedral geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms. In the second Mn site, Mn(2) is bonded in an octahedral geometry to two equivalent O(3), two equivalent O(5), and two equivalent O(6) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(6) atom. In the second C site, C(2) is bonded in a trigonal planar geometry to one O(3), one O(4), and one O(5) atom. There are six inequivalent O sites. In the first O site, O(6) is bonded in a bent 120 degrees geometry to one Mn(2) and one C(1) atom. In the second O site, O(1) is bonded in a bent 150 degrees geometry to one Mn(1) and one C(1) atom. In the third O site, O(2) is bonded in a bent 150 degrees geometry to one Mn(1) and one C(1) atom. In the fourth O site, O(3) is bonded in an L-shaped geometry to one Mn(2) and one C(2) atom. In the fifth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Mn(1) and one C(2) atom. In the sixth O site, O(5) is bonded in an L-shaped geometry to one Mn(2) and one C(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
