The structure described by CaMg6Zn crystallizes in the orthorhombic Amm2 space group. Ca(1) is bonded to two equivalent Mg(3), four equivalent Mg(1), four equivalent Mg(2), and two equivalent Zn(1) atoms to form CaMg10Zn2 cuboctahedra that share corners with six equivalent Ca(1)Mg10Zn2 cuboctahedra, faces with two equivalent Ca(1)Mg10Zn2 cuboctahedra, and faces with six equivalent Mg(4)Mg10Zn2 cuboctahedra. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 11-coordinate geometry to two equivalent Ca(1), two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(3), two equivalent Mg(4), and one Zn(1) atom. In the second Mg site, Mg(2) is bonded in a 12-coordinate geometry to two equivalent Ca(1), two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(3), two equivalent Mg(4), and two equivalent Zn(1) atoms. In the third Mg site, Mg(3) is bonded in a 12-coordinate geometry to two equivalent Ca(1), two equivalent Mg(4), four equivalent Mg(1), and four equivalent Mg(2) atoms. In the fourth Mg site, Mg(4) is bonded to two equivalent Mg(3), four equivalent Mg(1), four equivalent Mg(2), and two equivalent Zn(1) atoms to form distorted MgMg10Zn2 cuboctahedra that share corners with six equivalent Mg(4)Mg10Zn2 cuboctahedra, faces with two equivalent Mg(4)Mg10Zn2 cuboctahedra, and faces with six equivalent Ca(1)Mg10Zn2 cuboctahedra. Zn(1) is bonded in a 10-coordinate geometry to two equivalent Ca(1), two equivalent Mg(1), two equivalent Mg(4), and four equivalent Mg(2) atoms. is represented by the CIF card [CIF]
