Sr(Ag3O2)2 crystallizes in the orthorhombic Pnna space group. Sr(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form edge-sharing SrO6 octahedra. There are four inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a linear geometry to one O(1) and one O(2) atom. In the second Ag site, Ag(2) is bonded in a 2-coordinate geometry to two equivalent O(2) atoms. In the third Ag site, Ag(3) is bonded in a bent 150 degrees geometry to one O(1) and one O(2) atom. In the fourth Ag site, Ag(4) is bonded in a linear geometry to two equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to one Sr(1), one Ag(1), one Ag(3), and one Ag(4) atom. In the second O site, O(2) is bonded to two equivalent Sr(1), one Ag(1), one Ag(2), and one Ag(3) atom to form a mixture of corner and edge-sharing OSr2Ag3 trigonal bipyramids.
Sr(Ag3O2)2 crystallizes in the orthorhombic Pnna space group. Sr(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form edge-sharing SrO6 octahedra. Both Sr(1)-O(1) bond lengths are 2.49 Å. There are two shorter (2.46 Å) and two longer (2.69 Å) Sr(1)-O(2) bond lengths. There are four inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a linear geometry to one O(1) and one O(2) atom. The Ag(1)-O(1) bond length is 2.07 Å. The Ag(1)-O(2) bond length is 2.08 Å. In the second Ag site, Ag(2) is bonded in a 2-coordinate geometry to two equivalent O(2) atoms. Both Ag(2)-O(2) bond lengths are 2.38 Å. In the third Ag site, Ag(3) is bonded in a bent 150 degrees geometry to one O(1) and one O(2) atom. The Ag(3)-O(1) bond length is 2.12 Å. The Ag(3)-O(2) bond length is 2.10 Å. In the fourth Ag site, Ag(4) is bonded in a linear geometry to two equivalent O(1) atoms. Both Ag(4)-O(1) bond lengths are 2.10 Å. There are two inequivalent O sites.
