The material described by MgMoBiO5 crystallizes in the monoclinic P2_1/c space group. Mg(1) is bonded to one O(1), one O(2), one O(3), one O(5), and two equivalent O(4) atoms to form MgO6 octahedra that share corners with four equivalent Mo(1)O4 tetrahedra and  an edgeedge with one Mg(1)O6 octahedra. Mo(1) is bonded to one O(1), one O(2), one O(3), and one O(5) atom to form MoO4 tetrahedra that share corners with four equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 28-57°. Bi(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(5), and two equivalent O(4) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Mg(1), one Mo(1), and one Bi(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Mg(1), one Mo(1), and one Bi(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Mg(1), one Mo(1), and one Bi(1) atom. In the fourth O site, O(4) is bonded to two equivalent Mg(1) and two equivalent Bi(1) atoms to form distorted edge-sharing OMg2Bi2 tetrahedra. In the fifth O site, O(5) is bonded in a distorted T-shaped geometry to one Mg(1), one Mo(1), and one Bi(1) atom. is represented by the CIF card [CIF]
