The structure described by RbMg6Co crystallizes in the orthorhombic Amm2 space group. Rb(1) is bonded in a 10-coordinate geometry to two equivalent Mg(3), two equivalent Mg(4), four equivalent Mg(1), and two equivalent Co(1) atoms. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a distorted single-bond geometry to two equivalent Rb(1), two equivalent Mg(4), and one Co(1) atom. In the second Mg site, Mg(2) is bonded in a 6-coordinate geometry to four equivalent Mg(3) and two equivalent Co(1) atoms. In the third Mg site, Mg(3) is bonded in a distorted bent 120 degrees geometry to one Rb(1), two equivalent Mg(2), and two equivalent Co(1) atoms. In the fourth Mg site, Mg(4) is bonded in a 6-coordinate geometry to two equivalent Rb(1) and four equivalent Mg(1) atoms. Co(1) is bonded in a 6-coordinate geometry to two equivalent Rb(1), two equivalent Mg(1), two equivalent Mg(2), and four equivalent Mg(3) atoms. is represented by the CIF card [CIF]
