The crystal structure described by MgSbO3 is Orthorhombic Perovskite structured and crystallizes in the monoclinic P2_1/c space group. Mg(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form distorted MgO4 trigonal pyramids that share corners with four equivalent Sb(1)O6 octahedra, corners with four equivalent Sb(2)O6 octahedra, and corners with two equivalent Mg(1)O4 trigonal pyramids. The corner-sharing octahedral tilt angles range from 54-88°. 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 Sb(2)O6 octahedra and corners with eight equivalent Mg(1)O4 trigonal pyramids. The corner-sharing octahedral tilt angles range from 46-52°. 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 Sb(1)O6 octahedra and corners with eight equivalent Mg(1)O4 trigonal pyramids. The corner-sharing octahedral tilt angles range from 46-52°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Mg(1), one Sb(1), and one Sb(2) atom to form distorted corner-sharing OMg2Sb2 tetrahedra. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Mg(1), one Sb(1), and one Sb(2) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Mg(1), one Sb(1), and one Sb(2) atom. is represented by the CIF file [CIF]
