The compound described by RbMg6Ti crystallizes in the orthorhombic Amm2 space group. Rb(1) is bonded in a 14-coordinate geometry to two equivalent Mg(2), two equivalent Mg(4), four equivalent Mg(1), four equivalent Mg(3), and two equivalent Ti(1) atoms. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 9-coordinate geometry to two equivalent Rb(1), one Mg(1), two equivalent Mg(2), two equivalent Mg(4), and two equivalent Ti(1) atoms. In the second Mg site, Mg(2) is bonded in a 14-coordinate geometry to two equivalent Rb(1), two equivalent Mg(4), four equivalent Mg(1), four equivalent Mg(3), and two equivalent Ti(1) atoms. In the third Mg site, Mg(3) is bonded in a 4-coordinate geometry to two equivalent Rb(1), two equivalent Mg(2), two equivalent Mg(4), and two equivalent Ti(1) atoms. In the fourth Mg site, Mg(4) is bonded to two equivalent Rb(1), two equivalent Mg(2), four equivalent Mg(1), and four equivalent Mg(3) atoms to form a mixture of distorted face and corner-sharing MgRb2Mg10 cuboctahedra. Ti(1) is bonded in a 8-coordinate geometry to two equivalent Rb(1), two equivalent Mg(2), four equivalent Mg(1), and four equivalent Mg(3) atoms. is represented by the CIF card [CIF]
