The compound described by Na2Mg(CO3)2 crystallizes in the trigonal R-3 space group. Na(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. Mg(1) is bonded in an octahedral geometry to six equivalent O(1) atoms. C(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. O(1) is bonded in a 4-coordinate geometry to two equivalent Na(1), one Mg(1), and one C(1) atom. is represented by the CIF file [CIF]
