The structure described by MgCo2(BiO4)2 is beta indium sulfide-derived structured and crystallizes in the triclinic P-1 space group. Mg(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form MgO6 octahedra that share edges with two equivalent Co(1)O6 octahedra, edges with two equivalent Bi(1)O6 octahedra, and edges with two equivalent Bi(2)O6 octahedra. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form CoO6 octahedra that share edges with two equivalent Mg(1)O6 octahedra, edges with two equivalent Bi(1)O6 octahedra, and edges with two equivalent Bi(2)O6 octahedra. In the second Co site, Co(2) is bonded in a square co-planar geometry to two equivalent O(2) and two equivalent O(3) atoms. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form BiO6 octahedra that share edges with two equivalent Mg(1)O6 octahedra, edges with two equivalent Co(1)O6 octahedra, and edges with two equivalent Bi(2)O6 octahedra. In the second Bi site, Bi(2) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form BiO6 octahedra that share edges with two equivalent Mg(1)O6 octahedra, edges with two equivalent Co(1)O6 octahedra, and edges with two equivalent Bi(1)O6 octahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Mg(1), one Bi(1), and one Bi(2) atom. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one Mg(1), one Co(1), one Co(2), and one Bi(1) atom. In the third O site, O(3) is bonded in a see-saw-like geometry to one Mg(1), one Co(1), one Co(2), and one Bi(2) atom. In the fourth O site, O(4) is bonded in a distorted T-shaped geometry to one Co(1), one Bi(1), and one Bi(2) atom. is represented by the CIF card [CIF]
