ReSbO6 crystallizes in the monoclinic P2_1/m space group. Re(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms 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 28-32°. Sb(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms 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 31-38°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to 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 bent 150 degrees geometry to two equivalent Sb(1) atoms. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to two equivalent Re(1) atoms.
