The crystal structure described by BaMg(SbO3)2 is Corundum-derived structured and crystallizes in the trigonal P312 space group. Ba(1) is bonded to six equivalent O(1) atoms to form BaO6 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 49-64°. Mg(1) is bonded to six equivalent O(1) atoms to form distorted MgO6 octahedra that share corners with six equivalent Sb(2)O6 octahedra, edges with three equivalent Ba(1)O6 octahedra, and faces with two equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles are 34°. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to six equivalent O(1) atoms to form SbO6 octahedra that share corners with six equivalent Ba(1)O6 octahedra, edges with three equivalent Sb(2)O6 octahedra, and faces with two equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles are 49°. In the second Sb site, Sb(2) is bonded to six equivalent O(1) atoms to form distorted SbO6 octahedra that share corners with six equivalent Ba(1)O6 octahedra, corners with six equivalent Mg(1)O6 octahedra, and edges with three equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 34-64°. O(1) is bonded in a distorted see-saw-like geometry to one Ba(1), one Mg(1), one Sb(1), and one Sb(2) atom. is represented by the CIF file [CIF]
