The structure described by Mg(BiO2)4 is beta indium sulfide-derived structured and crystallizes in the triclinic P1 space group. Mg(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(7) atom to form distorted MgO6 octahedra that share corners with two equivalent Bi(4)O6 octahedra, edges with two equivalent Bi(1)O6 octahedra, edges with two equivalent Bi(2)O6 octahedra, and  a faceface with one Bi(4)O6 octahedra. The corner-sharing octahedral tilt angles range from 47-55°. There are four inequivalent Bi sites.
