The material described by BaMg(CO2)2 crystallizes in the monoclinic C2/m space group. Ba(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. Mg(1) is bonded in an octahedral geometry to two equivalent C(1) and four equivalent O(1) atoms. C(1) is bonded in a distorted trigonal planar geometry to one Mg(1) and two equivalent O(1) atoms. O(1) is bonded in a 4-coordinate geometry to two equivalent Ba(1), one Mg(1), and one C(1) atom. is represented by the CIF card [CIF]
