The crystal structure described by MgCo2(AgO3)2 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 six equivalent Co(1)O6 octahedra. Co(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form CoO6 octahedra that share edges with three equivalent Mg(1)O6 octahedra and edges with three equivalent Co(1)O6 octahedra. Ag(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to one Mg(1), two equivalent Co(1), and two equivalent Ag(1) atoms. In the second O site, O(2) is bonded in a 5-coordinate geometry to one Mg(1), two equivalent Co(1), and two equivalent Ag(1) atoms. In the third O site, O(3) is bonded in a 5-coordinate geometry to one Mg(1), two equivalent Co(1), and two equivalent Ag(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
