The compound described by MgZn(ReO4)2 crystallizes in the trigonal P-3 space group. Mg(1) is bonded to six equivalent O(2) atoms to form distorted MgO6 octahedra that share corners with six equivalent Re(1)O4 tetrahedra and faces with two equivalent Zn(1)O6 octahedra. Re(1) is bonded to one O(1) and three equivalent O(2) atoms to form ReO4 tetrahedra that share corners with three equivalent Mg(1)O6 octahedra and corners with three equivalent Zn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 30-55°. Zn(1) is bonded to six equivalent O(2) atoms to form ZnO6 octahedra that share corners with six equivalent Re(1)O4 tetrahedra and faces with two equivalent Mg(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one Re(1) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Mg(1), one Re(1), and one Zn(1) atom. is represented by the CIF file [CIF]
