The material structure described by RbKMg6 crystallizes in the orthorhombic Amm2 space group. Rb(1) is bonded in a 10-coordinate geometry to two equivalent K(1); two Mg(1,1); two equivalent Mg(4); and four Mg(2,2) atoms. K(1) is bonded in a 8-coordinate geometry to two equivalent Rb(1); two Mg(1,1); two equivalent Mg(3); and four Mg(2,2) atoms. There are seven inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 10-coordinate geometry to one Rb(1), one K(1), two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(3), and two equivalent Mg(4) atoms. In the second Mg site, Mg(1) is bonded in a 10-coordinate geometry to one Rb(1), one K(1), two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(3), and two equivalent Mg(4) atoms. In the third Mg site, Mg(2) is bonded in a 10-coordinate geometry to two equivalent Rb(1), two equivalent K(1), one Mg(3), one Mg(4), two equivalent Mg(1), and two equivalent Mg(2) atoms. In the fourth Mg site, Mg(2) is bonded in a 10-coordinate geometry to two equivalent Rb(1), two equivalent K(1), one Mg(3), one Mg(4), two equivalent Mg(1), and two equivalent Mg(2) atoms. In the fifth Mg site, Mg(3) is bonded in a 10-coordinate geometry to two equivalent K(1); two Mg(2,2); two equivalent Mg(4); and four Mg(1,1) atoms. In the sixth Mg site, Mg(4) is bonded in a 10-coordinate geometry to two equivalent Rb(1); two Mg(2,2); two equivalent Mg(3); and four Mg(1,1) atoms. In the seventh Mg site, Mg(1) is bonded in a 10-coordinate geometry to one Rb(1), one K(1), two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(3), and two equivalent Mg(4) atoms. is represented by the CIF card [CIF]
