The crystal structure described by RbMg(O2Br)3 crystallizes in the monoclinic C2/c space group. Rb(1) is bonded in a 4-coordinate geometry to two equivalent O(2) and two equivalent O(3) atoms. Mg(1) is bonded in an octahedral geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Mg(1), one Br(1), and one Br(2) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Rb(1), one Mg(1), and one Br(2) atom. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to one Rb(1), one Mg(1), and one Br(2) atom. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a linear geometry to two equivalent O(1) atoms. In the second Br site, Br(2) is bonded in a distorted T-shaped geometry to one O(1), one O(2), and one O(3) atom. is represented by the CIF file [CIF]
