The crystal structure described by CdTa2O6 crystallizes in the orthorhombic Pbcn space group. Ta(1) is bonded in a 6-coordinate geometry to one O(1), two equivalent O(2), and three equivalent O(3) atoms. Cd(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form edge-sharing CdO6 octahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Ta(1) and two equivalent Cd(1) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to two equivalent Ta(1) and one Cd(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to three equivalent Ta(1) atoms. is represented by the CIF card [CIF]
