The structure described by Sr2Mg(AgO2)2 crystallizes in the triclinic P1 space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form distorted SrO4 tetrahedra that share corners with four equivalent Mg(1)O4 tetrahedra. In the second Sr site, Sr(2) is bonded in a distorted see-saw-like geometry to one O(1), one O(2), one O(3), and one O(4) atom. Mg(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form MgO4 tetrahedra that share corners with four equivalent Sr(1)O4 tetrahedra. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted bent 150 degrees geometry to one O(2) and one O(4) atom. In the second Ag site, Ag(2) is bonded in a distorted bent 150 degrees geometry to one O(1) and one O(3) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted see-saw-like geometry to one Sr(1), one Sr(2), one Mg(1), and one Ag(2) atom. In the second O site, O(2) is bonded in a distorted see-saw-like geometry to one Sr(1), one Sr(2), one Mg(1), and one Ag(1) atom. In the third O site, O(3) is bonded in a rectangular see-saw-like geometry to one Sr(1), one Sr(2), one Mg(1), and one Ag(2) atom. In the fourth O site, O(4) is bonded in a rectangular see-saw-like geometry to one Sr(1), one Sr(2), one Mg(1), and one Ag(1) atom. is represented by the CIF card [CIF]
