The crystal structure described by La2Ag2O5 is Aluminum carbonitride-like structured and crystallizes in the orthorhombic Ima2 space group. La(1) is bonded in a 5-coordinate geometry to one O(3), two equivalent O(1), and two equivalent O(2) atoms. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form AgO6 octahedra that share corners with four equivalent Ag(1)O6 octahedra and corners with two equivalent Ag(2)O4 tetrahedra. The corner-sharing octahedral tilt angles are 30°. In the second Ag site, Ag(2) is bonded to two equivalent O(2) and two equivalent O(3) atoms to form distorted AgO4 tetrahedra that share corners with two equivalent Ag(1)O6 octahedra and corners with two equivalent Ag(2)O4 tetrahedra. The corner-sharing octahedral tilt angles are 47°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent La(1) and two equivalent Ag(1) atoms. In the second O site, O(2) is bonded to two equivalent La(1), one Ag(1), and one Ag(2) atom to form distorted corner-sharing OLa2Ag2 tetrahedra. In the third O site, O(3) is bonded to two equivalent La(1) and two equivalent Ag(2) atoms to form distorted corner-sharing OLa2Ag2 tetrahedra. is represented by the CIF file [CIF]
