The crystal structure described by CsCaMg6 crystallizes in the orthorhombic Amm2 space group. Cs(1) is bonded to two equivalent Ca(1), two equivalent Mg(4), four equivalent Mg(1), and four equivalent Mg(2) atoms to form a mixture of distorted face and corner-sharing CsCa2Mg10 cuboctahedra. Ca(1) is bonded in a 12-coordinate geometry to two equivalent Cs(1), two equivalent Mg(3), four equivalent Mg(1), and four equivalent Mg(2) atoms. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 11-coordinate geometry to two equivalent Cs(1), two equivalent Ca(1), one Mg(1), two equivalent Mg(2), two equivalent Mg(3), and two equivalent Mg(4) atoms. In the second Mg site, Mg(2) is bonded in a 9-coordinate geometry to two equivalent Cs(1), two equivalent Ca(1), one Mg(2), one Mg(3), one Mg(4), and two equivalent Mg(1) atoms. In the third Mg site, Mg(3) is bonded in a 8-coordinate geometry to two equivalent Ca(1), two equivalent Mg(2), and four equivalent Mg(1) atoms. In the fourth Mg site, Mg(4) is bonded in a 8-coordinate geometry to two equivalent Cs(1), two equivalent Mg(2), and four equivalent Mg(1) atoms. is represented by the CIF file [CIF]
