The material structure described by MgAg3(AsO4)2 crystallizes in the triclinic P1 space group. Mg(1) is bonded in a 4-coordinate geometry to one O(1), one O(6), one O(7), and one O(8) atom. There are three inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a rectangular see-saw-like geometry to one O(1), one O(2), one O(3), and one O(4) atom. In the second Ag site, Ag(2) is bonded in a rectangular see-saw-like geometry to one O(2), one O(4), one O(5), and one O(8) atom. In the third Ag site, Ag(3) is bonded in a rectangular see-saw-like geometry to one O(2), one O(3), one O(5), and one O(7) atom. There are two inequivalent As sites. In the first As site, As(1) is bonded in a distorted tetrahedral geometry to one O(1), one O(2), one O(7), and one O(8) atom. In the second As site, As(2) is bonded in a tetrahedral geometry to one O(3), one O(4), one O(5), and one O(6) atom. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to one Mg(1), one Ag(1), and one As(1) atom. In the second O site, O(2) is bonded in a distorted tetrahedral geometry to one Ag(1), one Ag(2), one Ag(3), and one As(1) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to one Ag(1), one Ag(3), and one As(2) atom. In the fourth O site, O(4) is bonded in a trigonal planar geometry to one Ag(1), one Ag(2), and one As(2) atom. In the fifth O site, O(5) is bonded in a trigonal planar geometry to one Ag(2), one Ag(3), and one As(2) atom. In the sixth O site, O(6) is bonded in a linear geometry to one Mg(1) and one As(2) atom. In the seventh O site, O(7) is bonded in a distorted trigonal non-coplanar geometry to one Mg(1), one Ag(3), and one As(1) atom. In the eighth O site, O(8) is bonded in a distorted trigonal non-coplanar geometry to one Mg(1), one Ag(2), and one As(1) atom. is represented by the CIF card [CIF]
