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.
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. There are four shorter (2.79 Å) and four longer (2.83 Å) Ba(1)-O(1) bond lengths. Mg(1) is bonded in an octahedral geometry to two equivalent C(1) and four equivalent O(1) atoms. Both Mg(1)-C(1) bond lengths are 2.37 Å. All Mg(1)-O(1) bond lengths are 2.18 Å. C(1) is bonded in a distorted trigonal planar geometry to one Mg(1) and two equivalent O(1) atoms. Both C(1)-O(1) bond lengths are 1.32 Å. O(1) is bonded in a 4-coordinate geometry to two equivalent Ba(1), one Mg(1), and one C(1) atom.
