The crystal structure described by Ba2Mg(BO3)2 crystallizes in the trigonal R-3m space group. Ba(1) is bonded in a 10-coordinate geometry to one B(1) and nine equivalent O(1) atoms. Mg(1) is bonded in an octahedral geometry to six equivalent O(1) atoms. B(1) is bonded in a trigonal planar geometry to one Ba(1) and three equivalent O(1) atoms. O(1) is bonded in a 2-coordinate geometry to three equivalent Ba(1), one Mg(1), and one B(1) atom. is represented by the CIF file [CIF]
