The material described by RbMg3 crystallizes in the hexagonal P6_3/mmc space group. Rb(1) is bonded in a 6-coordinate geometry to six equivalent Mg(1) atoms. Mg(1) is bonded in a 8-coordinate geometry to two equivalent Rb(1) and six equivalent Mg(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
