The material described by MgRe2(SbO6)2 crystallizes in the monoclinic Pm space group. Mg(1) is bonded in a 8-coordinate geometry to one O(6), one O(7), two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms. Re(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(6), and one O(8) atom to form ReO6 octahedra that share corners with two equivalent Re(1)O6 octahedra and corners with four equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 29-40°. Sb(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(7) atom to form SbO6 octahedra that share corners with two equivalent Sb(1)O6 octahedra and corners with four equivalent Re(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 32-41°. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Mg(1), one Re(1), and one Sb(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Re(1) and one Sb(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Mg(1), one Re(1), and one Sb(1) atom. In the fourth O site, O(4) is bonded in a T-shaped geometry to one Mg(1), one Re(1), and one Sb(1) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to two equivalent Sb(1) atoms. In the sixth O site, O(6) is bonded in a T-shaped geometry to one Mg(1) and two equivalent Re(1) atoms. In the seventh O site, O(7) is bonded in a distorted trigonal non-coplanar geometry to one Mg(1) and two equivalent Sb(1) atoms. In the eighth O site, O(8) is bonded in a bent 150 degrees geometry to two equivalent Re(1) atoms. is represented by the CIF card [CIF]
