Cd3(BO3)2 crystallizes in the orthorhombic Pnnm space group. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form a mixture of corner and edge-sharing CdO6 octahedra. The corner-sharing octahedral tilt angles range from 60-73°. In the second Cd site, Cd(2) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing CdO6 octahedra. The corner-sharing octahedral tilt angles are 73°. B(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Cd(2), two equivalent Cd(1), and one B(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Cd(2), two equivalent Cd(1), and one B(1) atom.

In the first Cd site, Cd(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form a mixture of corner and edge-sharing CdO6 octahedra. The corner-sharing octahedral tilt angles range from 60-73°. Both Cd(1)-O(2) bond lengths are 2.37 Å. There are two shorter (2.27 Å) and two longer (2.35 Å) Cd(1)-O(1) bond lengths. In the second Cd site, Cd(2) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing CdO6 octahedra. The corner-sharing octahedral tilt angles are 73°. Both Cd(2)-O(2) bond lengths are 2.29 Å. All Cd(2)-O(1) bond lengths are 2.34 Å. B(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(1) atoms. The B(1)-O(2) bond length is 1.38 Å. Both B(1)-O(1) bond lengths are 1.39 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Cd(2), two equivalent Cd(1), and one B(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Cd(2), two equivalent Cd(1), and one B(1) atom.
