The structure described by MgCo2(BiO4)2 is beta indium sulfide-derived structured and crystallizes in the orthorhombic Imm2 space group. Mg(1) is bonded to two equivalent O(2) and two equivalent O(4) atoms to form MgO4 tetrahedra that share corners with six equivalent Co(1)O6 octahedra and corners with six equivalent Bi(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 53-65°. Co(1) is bonded to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms to form CoO6 octahedra that share corners with three equivalent Mg(1)O4 tetrahedra, edges with two equivalent Co(1)O6 octahedra, and edges with four equivalent Bi(1)O6 octahedra. Bi(1) is bonded to one O(2), one O(3), two equivalent O(1), and two equivalent O(4) atoms to form BiO6 octahedra that share corners with three equivalent Mg(1)O4 tetrahedra, edges with two equivalent Bi(1)O6 octahedra, and edges with four equivalent Co(1)O6 octahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Co(1) and two equivalent Bi(1) atoms. In the second O site, O(2) is bonded to one Mg(1), two equivalent Co(1), and one Bi(1) atom to form a mixture of distorted corner and edge-sharing OMgCo2Bi tetrahedra. In the third O site, O(3) is bonded in a distorted T-shaped geometry to two equivalent Co(1) and one Bi(1) atom. In the fourth O site, O(4) is bonded in a distorted rectangular see-saw-like geometry to one Mg(1), one Co(1), and two equivalent Bi(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
