The compound described by UCdO4 is Calcite-like structured and crystallizes in the orthorhombic Cmmm space group. U(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form UO6 octahedra that share corners with eight equivalent Cd(1)O6 octahedra and edges with two equivalent U(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 50-54°. Cd(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CdO6 octahedra that share corners with eight equivalent U(1)O6 octahedra and edges with two equivalent Cd(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 50-54°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one U(1) and two equivalent Cd(1) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to two equivalent U(1) and one Cd(1) atom. is represented by the CIF file [CIF]
