The structure described by MgTiZn(BiO3)2 crystallizes in the monoclinic Cm space group. Mg(1) is bonded in a 3-coordinate geometry to one Bi(1), one O(3), and two equivalent O(1) atoms. Ti(1) is bonded to one O(3), one O(4), and two equivalent O(2) atoms to form TiO4 tetrahedra that share corners with three equivalent Bi(2)O5 square pyramids. Zn(1) is bonded in a distorted rectangular see-saw-like geometry to one O(3), one O(4), and two equivalent O(1) atoms. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 5-coordinate geometry to one Mg(1), two equivalent O(1), and two equivalent O(2) atoms. In the second Bi site, Bi(2) is bonded to one O(4), two equivalent O(1), and two equivalent O(2) atoms to form BiO5 square pyramids that share corners with three equivalent Ti(1)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Mg(1), one Zn(1), one Bi(1), and one Bi(2) atom to form distorted edge-sharing OMgZnBi2 tetrahedra. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Ti(1), one Bi(1), and one Bi(2) atom. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to one Mg(1), one Ti(1), and one Zn(1) atom. In the fourth O site, O(4) is bonded in a trigonal planar geometry to one Ti(1), one Zn(1), and one Bi(2) atom. is represented by the CIF file [CIF]
