The compound described by MgAg2(GeO3)2 crystallizes in the monoclinic P2/m space group. Mg(1) is bonded in a square co-planar geometry to four equivalent O(2) atoms. Ag(1) is bonded in a 5-coordinate geometry to one O(2), two equivalent O(1), and two equivalent O(3) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to two equivalent O(3) and four equivalent O(1) atoms to form a mixture of corner and edge-sharing GeO6 octahedra. The corner-sharing octahedral tilt angles are 34°. In the second Ge site, Ge(2) is bonded to two equivalent O(3) and four equivalent O(2) atoms to form a mixture of corner and edge-sharing GeO6 octahedra. The corner-sharing octahedral tilt angles are 34°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Ag(1) and two equivalent Ge(1) atoms. In the second O site, O(2) is bonded to two equivalent Mg(1), one Ag(1), and two equivalent Ge(2) atoms to form a mixture of distorted corner and edge-sharing OMg2AgGe2 square pyramids. In the third O site, O(3) is bonded in a 4-coordinate geometry to two equivalent Ag(1), one Ge(1), and one Ge(2) atom. is represented by the CIF card [CIF]
