CdBC12N8H12Br crystallizes in the tetragonal P4/n space group. Cd(1) is bonded to four equivalent N(2) and two equivalent Br(1) atoms to form distorted corner-sharing CdBr2N4 octahedra. The corner-sharing octahedra are not tilted. All Cd(1)-N(2) bond lengths are 2.33 Å. There is one shorter (2.79 Å) and one longer (3.20 Å) Cd(1)-Br(1) bond length. B(1) is bonded in a tetrahedral geometry to four equivalent N(1) atoms. All B(1)-N(1) bond lengths are 1.55 Å. There are three inequivalent C sites. In the first C site, C(2) is bonded in a distorted bent 120 degrees geometry to one C(1), one N(2), and one H(2) atom. The C(2)-C(1) bond length is 1.37 Å. The C(2)-N(2) bond length is 1.38 Å. The C(2)-H(2) bond length is 1.08 Å. In the second C site, C(3) is bonded in a trigonal planar geometry to one N(1), one N(2), and one H(3) atom. The C(3)-N(1) bond length is 1.37 Å. The C(3)-N(2) bond length is 1.33 Å. The C(3)-H(3) bond length is 1.08 Å. In the third C site, C(1) is bonded in a distorted bent 120 degrees geometry to one C(2), one N(1), and one H(1) atom. The C(1)-N(1) bond length is 1.39 Å. The C(1)-H(1) bond length is 1.08 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one B(1), one C(1), and one C(3) atom. In the second N site, N(2) is bonded in a distorted trigonal planar geometry to one Cd(1), one C(2), and one C(3) atom. There are three inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(2) atom. In the third H site, H(3) is bonded in a single-bond geometry to one C(3) atom. Br(1) is bonded in a linear geometry to two equivalent Cd(1) atoms. Linkers: 2 c1ncn(c1)[B](n1cncc1)(n1cncc1)n1cncc1.
