The compound described by La2Cd2O5 is Aluminum carbonitride-like structured and crystallizes in the orthorhombic Pnma space group. La(1) is bonded in a 6-coordinate geometry to one O(2), two equivalent O(1), and three equivalent O(3) atoms. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded to two equivalent O(1) and four equivalent O(3) atoms to form CdO6 octahedra that share corners with four equivalent Cd(1)O6 octahedra and corners with two equivalent Cd(2)O4 tetrahedra. The corner-sharing octahedral tilt angles are 40°. In the second Cd site, Cd(2) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form CdO4 tetrahedra that share corners with two equivalent Cd(1)O6 octahedra and corners with two equivalent Cd(2)O4 tetrahedra. The corner-sharing octahedral tilt angles are 59°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent La(1), one Cd(1), and one Cd(2) atom to form corner-sharing OLa2Cd2 tetrahedra. In the second O site, O(2) is bonded to two equivalent La(1) and two equivalent Cd(2) atoms to form corner-sharing OLa2Cd2 tetrahedra. In the third O site, O(3) is bonded in a 5-coordinate geometry to three equivalent La(1) and two equivalent Cd(1) atoms. is represented by the CIF card [CIF]
