The material structure described by CrCdO4 crystallizes in the orthorhombic Cmcm space group. Cr(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form CrO4 tetrahedra that share corners with six equivalent Cd(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 45-54°. Cd(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CdO6 octahedra that share corners with six equivalent Cr(1)O4 tetrahedra and edges with two equivalent Cd(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Cr(1) and two equivalent Cd(1) atoms. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Cr(1) and one Cd(1) atom. is represented by the CIF file [CIF]
