Cd(BO2)2 crystallizes in the trigonal R3c space group. Cd(1) is bonded in a 6-coordinate geometry to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms. There are two inequivalent B sites. In the first B site, B(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(1) atoms. In the second B site, B(2) is bonded in a trigonal planar geometry to one O(3) and two equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Cd(1) and two equivalent B(1) atoms. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Cd(1) and one B(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Cd(1) and one B(2) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Cd(1) and two equivalent B(2) atoms.
