Pb3Cd3(BO3)4 crystallizes in the hexagonal P6_3/m space group. Cd(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form edge-sharing CdO6 octahedra. 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(3) atoms. In the second B site, B(2) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. Pb(1) is bonded in a 5-coordinate geometry to one O(1) and four equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(3) is bonded in a 1-coordinate geometry to one Cd(1), one B(1), and two equivalent Pb(1) atoms. In the second O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Cd(1), one B(2), and one Pb(1) atom. In the third O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Cd(1) and one B(1) atom.
