The material described by Cd3Zn3B4O12 crystallizes in the trigonal R3 space group. Cd(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form distorted CdO4 tetrahedra that share corners with four equivalent Zn(1)O4 tetrahedra. Zn(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form ZnO4 tetrahedra that share corners with four equivalent Cd(1)O4 tetrahedra. There are four inequivalent B sites. In the first B site, B(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. In the second B site, B(2) is bonded in a trigonal planar geometry to three equivalent O(2) atoms. In the third B site, B(3) is bonded in a trigonal planar geometry to three equivalent O(3) atoms. In the fourth B site, B(4) is bonded in a trigonal planar geometry to three equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one Cd(1), one Zn(1), and one B(2) atom. In the second O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to one Cd(1), one Zn(1), and one B(3) atom. In the third O site, O(4) is bonded in a distorted trigonal planar geometry to one Cd(1), one Zn(1), and one B(4) atom. In the fourth O site, O(1) is bonded in a distorted trigonal planar geometry to one Cd(1), one Zn(1), and one B(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
