MgRhSbO4 is Corundum-derived structured and crystallizes in the monoclinic P2 space group. Mg(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form MgO6 octahedra that share edges with two equivalent Mg(1)O6 octahedra and edges with four equivalent Rh(1)O6 octahedra. Rh(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form RhO6 octahedra that share edges with two equivalent Rh(1)O6 octahedra and edges with four equivalent Mg(1)O6 octahedra. Sb(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Mg(1), two equivalent Rh(1), and one Sb(1) atom to form a mixture of edge and corner-sharing OMgSbRh2 trigonal pyramids. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to two equivalent Mg(1), one Rh(1), and one Sb(1) atom.

Mg(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form MgO6 octahedra that share edges with two equivalent Mg(1)O6 octahedra and edges with four equivalent Rh(1)O6 octahedra. Both Mg(1)-O(1) bond lengths are 2.03 Å. There are two shorter (2.08 Å) and two longer (2.15 Å) Mg(1)-O(2) bond lengths. Rh(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form RhO6 octahedra that share edges with two equivalent Rh(1)O6 octahedra and edges with four equivalent Mg(1)O6 octahedra. Both Rh(1)-O(2) bond lengths are 2.10 Å. There are two shorter (2.05 Å) and two longer (2.12 Å) Rh(1)-O(1) bond lengths. Sb(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. Both Sb(1)-O(1) bond lengths are 2.29 Å. Both Sb(1)-O(2) bond lengths are 2.16 Å.
