IrAg3O4 crystallizes in the tetragonal P4_122 space group. Ir(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form edge-sharing IrO6 octahedra. There are three inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. In the second Ag site, Ag(2) is bonded in a bent 150 degrees geometry to two equivalent O(1) atoms. In the third Ag site, Ag(3) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to one Ir(1), one Ag(2), one Ag(3), and two equivalent Ag(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Ir(1) and one Ag(3) atom.
IrAg3O4 crystallizes in the tetragonal P4_122 space group. Ir(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form edge-sharing IrO6 octahedra. Both Ir(1)-O(1) bond lengths are 1.96 Å. There are two shorter (1.99 Å) and two longer (2.01 Å) Ir(1)-O(2) bond lengths. There are three inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. There are two shorter (2.44 Å) and two longer (2.45 Å) Ag(1)-O(1) bond lengths. In the second Ag site, Ag(2) is bonded in a bent 150 degrees geometry to two equivalent O(1) atoms. Both Ag(2)-O(1) bond lengths are 2.18 Å. In the third Ag site, Ag(3) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. Both Ag(3)-O(1) bond lengths are 2.54 Å. Both Ag(3)-O(2) bond lengths are 2.33 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to one Ir(1), one Ag(2), one Ag(3), and two equivalent Ag(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Ir(1) and one Ag(3) atom.
