Materials Data on BaMg(CO2)2 by Materials Project
BaMg(CO2)2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Ba2+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.79 Å) and four longer (2.83 Å) Ba–O bond lengths. Mg2+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Mg–O bond lengths are 2.18 Å. C2+ is bonded in a bent 120 degrees geometry to two equivalent O2- atoms. Both C–O bond lengths are 1.32 Å. O2- is bonded in a 4-coordinate geometry to two equivalent Ba2+, one Mg2+, and one C2+ atom.
