MgCd2Te2(MoO6)2 crystallizes in the tetragonal P-4 space group. Mg(1) is bonded to four equivalent O(1) atoms to form MgO4 tetrahedra that share corners with four equivalent Mo(1)O4 tetrahedra. Mo(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form distorted MoO4 tetrahedra that share corners with two equivalent Mg(1)O4 tetrahedra. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 8-coordinate geometry to four equivalent O(2) and four equivalent O(3) atoms. In the second Cd site, Cd(2) is bonded in a tetrahedral geometry to four equivalent O(3) atoms. Te(1) is bonded in a distorted see-saw-like geometry to two equivalent O(2) and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Mg(1) and one Mo(1) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to one Mo(1), one Cd(1), and one Te(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Cd(1), one Cd(2), and one Te(1) atom.
