The material structure described by MgRb crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 4-coordinate geometry to two equivalent Mg(1) and two equivalent Mg(2) atoms. In the second Rb site, Rb(2) is bonded in a 6-coordinate geometry to two equivalent Mg(2) and four equivalent Mg(1) atoms. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 8-coordinate geometry to one Rb(1), four equivalent Rb(2), one Mg(1), and two equivalent Mg(2) atoms. In the second Mg site, Mg(2) is bonded in a 10-coordinate geometry to two equivalent Rb(1), four equivalent Rb(2), and four equivalent Mg(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
