The crystal structure described by MgBi2(SbO4)2 crystallizes in the triclinic P1 space group. Mg(1) is bonded in a distorted see-saw-like geometry to one O(1), one O(2), one O(4), and one O(5) atom. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a distorted rectangular see-saw-like geometry to one O(1), one O(3), one O(4), and one O(8) atom. In the second Bi site, Bi(2) is bonded in a 3-coordinate geometry to one O(2), one O(3), and one O(6) atom. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to one O(2), one O(4), one O(5), one O(6), one O(7), and one O(8) atom to form corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles range from 30-52°. In the second Sb site, Sb(2) is bonded to one O(1), one O(3), one O(5), one O(6), one O(7), and one O(8) atom to form corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles range from 30-52°. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to one Mg(1), one Bi(1), and one Sb(2) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Mg(1), one Bi(2), and one Sb(1) atom. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to one Bi(1), one Bi(2), and one Sb(2) atom. In the fourth O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to one Mg(1), one Bi(1), and one Sb(1) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to one Mg(1), one Sb(1), and one Sb(2) atom. In the sixth O site, O(6) is bonded in a 3-coordinate geometry to one Bi(2), one Sb(1), and one Sb(2) atom. In the seventh O site, O(7) is bonded in a distorted bent 120 degrees geometry to one Sb(1) and one Sb(2) atom. In the eighth O site, O(8) is bonded in a 3-coordinate geometry to one Bi(1), one Sb(1), and one Sb(2) atom. is represented by the CIF file [CIF]
