The compound described by MgAg2(GeO3)2 crystallizes in the orthorhombic Pmm2 space group. Mg(1) is bonded to two equivalent O(1) and two equivalent O(3) atoms to form MgO4 tetrahedra that share corners with four equivalent Ge(1)O5 square pyramids and corners with two equivalent Mg(1)O4 tetrahedra. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 4-coordinate geometry to two equivalent O(2) and two equivalent O(4) atoms. In the second Ag site, Ag(2) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(3) atoms. Ge(1) is bonded to one O(2), two equivalent O(1), and two equivalent O(4) atoms to form GeO5 square pyramids that share  a cornercorner with one Ge(1)O5 square pyramid, corners with two equivalent Mg(1)O4 tetrahedra, and edges with two equivalent Ge(1)O5 square pyramids. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Mg(1), one Ag(2), and two equivalent Ge(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Ag(1) and two equivalent Ge(1) atoms. In the third O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Mg(1) and two equivalent Ag(2) atoms. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Ag(1) and two equivalent Ge(1) atoms. is represented by the CIF card [CIF]
