The crystal structure described by MgAg4(MoO4)2 crystallizes in the cubic F-43m space group. Mg(1) is bonded in a body-centered cubic geometry to four equivalent Ag(1) and four equivalent O(1) atoms. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded to four equivalent O(2) atoms to form MoO4 tetrahedra that share corners with twelve equivalent Ag(1)MgO3 tetrahedra. In the second Mo site, Mo(2) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. Ag(1) is bonded to one Mg(1) and three equivalent O(2) atoms to form distorted AgMgO3 tetrahedra that share corners with three equivalent Mo(1)O4 tetrahedra, corners with three equivalent Ag(1)MgO3 tetrahedra, and edges with three equivalent Ag(1)MgO3 tetrahedra. There are two inequivalent O sites. In the first O site, O(2) is bonded in a 4-coordinate geometry to one Mo(1) and three equivalent Ag(1) atoms. In the second O site, O(1) is bonded in a linear geometry to one Mg(1) and one Mo(2) atom. is represented by the CIF card [CIF]
