Cd4B6O13 crystallizes in the cubic I-43m space group. Cd(1) is bonded in a 4-coordinate geometry to one O(2) and three equivalent O(1) atoms. B(1) is bonded to four equivalent O(1) atoms to form corner-sharing BO4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Cd(1) and two equivalent B(1) atoms. In the second O site, O(2) is bonded in a tetrahedral geometry to four equivalent Cd(1) atoms.
