The compound described by MgMn(ReO4)2 crystallizes in the trigonal P-3m1 space group. Mg(1) is bonded to six equivalent O(2) atoms to form MgO6 octahedra that share corners with six equivalent Re(1)O4 tetrahedra and faces with two equivalent Mn(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 Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 30-55°. Mn(1) is bonded to six equivalent O(2) atoms to form distorted MnO6 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 Mn(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
