Mg(AgO2)2 crystallizes in the orthorhombic Pbcm space group. Mg(1) is bonded in a 6-coordinate geometry to two equivalent O(2), two equivalent O(3), and four equivalent O(1) atoms. Ag(1) is bonded to one O(3), two equivalent O(1), and two equivalent O(2) atoms to form a mixture of distorted corner and edge-sharing AgO5 square pyramids. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Mg(1) and two equivalent Ag(1) atoms to form a mixture of distorted corner and edge-sharing OMg2Ag2 tetrahedra. In the second O site, O(2) is bonded in a 6-coordinate geometry to two equivalent Mg(1) and four equivalent Ag(1) atoms. In the third O site, O(3) is bonded to two equivalent Mg(1) and two equivalent Ag(1) atoms to form a mixture of corner and edge-sharing OMg2Ag2 tetrahedra.
Mg(AgO2)2 crystallizes in the orthorhombic Pbcm space group. Mg(1) is bonded in a 6-coordinate geometry to two equivalent O(2), two equivalent O(3), and four equivalent O(1) atoms. Both Mg(1)-O(2) bond lengths are 2.72 Å. There is one shorter (2.15 Å) and one longer (2.19 Å) Mg(1)-O(3) bond length. There are two shorter (2.23 Å) and two longer (2.33 Å) Mg(1)-O(1) bond lengths. Ag(1) is bonded to one O(3), two equivalent O(1), and two equivalent O(2) atoms to form a mixture of distorted corner and edge-sharing AgO5 square pyramids. The Ag(1)-O(3) bond length is 2.06 Å. There is one shorter (2.06 Å) and one longer (2.09 Å) Ag(1)-O(1) bond length. There is one shorter (2.00 Å) and one longer (2.58 Å) Ag(1)-O(2) bond length. There are three inequivalent O sites.
