CdH24(C5N2)6 crystallizes in the cubic Pa-3 space group. Cd(1) is bonded in an octahedral geometry to six equivalent N(2) atoms. All Cd(1)-N(2) bond lengths are 2.34 Å. There are five inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one C(3) and two equivalent C(2) atoms. The C(1)-C(3) bond length is 1.46 Å. There is one shorter (1.39 Å) and one longer (1.40 Å) C(1)-C(2) bond length. In the second C site, C(2) is bonded in a distorted single-bond geometry to two equivalent C(1) and one H(2) atom. The C(2)-H(2) bond length is 0.95 Å. In the third C site, C(3) is bonded in a 3-coordinate geometry to one C(1), one C(4), and one N(1) atom. The C(3)-C(4) bond length is 1.35 Å. The C(3)-N(1) bond length is 1.36 Å. In the fourth C site, C(4) is bonded in a distorted bent 120 degrees geometry to one C(3), one N(2), and one H(3) atom. The C(4)-N(2) bond length is 1.36 Å. The C(4)-H(3) bond length is 0.95 Å. In the fifth C site, C(5) is bonded in a trigonal planar geometry to one N(1), one N(2), and one H(4) atom. The C(5)-N(1) bond length is 1.35 Å. The C(5)-N(2) bond length is 1.30 Å. The C(5)-H(4) bond length is 0.95 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one C(3), one C(5), and one H(1) atom. The N(1)-H(1) bond length is 0.88 Å. In the second N site, N(2) is bonded in a distorted trigonal planar geometry to one Cd(1), one C(4), and one C(5) atom. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one N(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(4) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one C(5) atom.
