The compound described by MgTiZn(BiO3)2 crystallizes in the monoclinic Cm space group. Mg(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(3) atom. Ti(1) is bonded to one O(1), one O(4), one O(5), and two equivalent O(2) atoms to form distorted TiO5 trigonal bipyramids that share corners with three equivalent Zn(1)O4 tetrahedra. Zn(1) is bonded to one O(3), one O(5), and two equivalent O(2) atoms to form ZnO4 tetrahedra that share corners with three equivalent Ti(1)O5 trigonal bipyramids. Bi(1) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(3), one O(4), and one O(5) atom. There are five inequivalent O sites. In the first O site, O(1) is bonded to one Mg(1), one Ti(1), and two equivalent Bi(1) atoms to form OMgTiBi2 tetrahedra that share corners with three equivalent O(3)MgZnBi2 tetrahedra and corners with three equivalent O(5)TiZnBi2 tetrahedra.
