The compound described by MgHg(SbO3)2 is Ilmenite-derived structured and crystallizes in the monoclinic C2 space group. Mg(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form MgO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra, edges with three equivalent Hg(1)O6 octahedra, and faces with two equivalent Sb(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 39-40°. Hg(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form HgO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra, corners with six equivalent Sb(2)O6 octahedra, and edges with three equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 46-60°. There are two inequivalent Sb sites. In the first Sb site, 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 six equivalent Mg(1)O6 octahedra, corners with six equivalent Hg(1)O6 octahedra, and edges with three equivalent Sb(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 39-60°. In the second Sb site, Sb(2) 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 six equivalent Hg(1)O6 octahedra, edges with three equivalent Sb(1)O6 octahedra, and faces with two equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles are 46°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to one Mg(1), one Hg(1), one Sb(1), and one Sb(2) atom. In the second O site, O(2) is bonded in a distorted rectangular see-saw-like geometry to one Mg(1), one Hg(1), one Sb(1), and one Sb(2) atom. In the third O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to one Mg(1), one Hg(1), one Sb(1), and one Sb(2) atom. is represented by the CIF file [CIF]
