CdC20N8H16Cl(CH)4 crystallizes in the tetragonal P4/n space group. The structure consists of eight 02329_fluka molecules inside a CdC20N8H16Cl framework. In the CdC20N8H16Cl framework, Cd(1) is bonded to four equivalent N(1) and two equivalent Cl(1) atoms to form corner-sharing CdN4Cl2 octahedra. The corner-sharing octahedra are not tilted. All Cd(1)-N(1) bond lengths are 2.34 Å. There is one shorter (2.60 Å) and one longer (2.61 Å) Cd(1)-Cl(1) bond length. There are five inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(1) atom. The C(1)-N(1) bond length is 1.34 Å. The C(1)-H(1) bond length is 0.93 Å. In the second C site, C(3) is bonded in a distorted single-bond geometry to one C(4) and one H(3) atom. The C(3)-C(4) bond length is 1.38 Å. The C(3)-H(3) bond length is 0.93 Å. In the third C site, C(4) is bonded in a trigonal planar geometry to one C(3), one C(5), and one C(6) atom. The C(4)-C(5) bond length is 1.39 Å. The C(4)-C(6) bond length is 1.47 Å. In the fourth C site, C(5) is bonded in a distorted bent 120 degrees geometry to one C(4), one N(1), and one H(4) atom. The C(5)-N(1) bond length is 1.33 Å. The C(5)-H(4) bond length is 0.93 Å. In the fifth C site, C(6) is bonded in a distorted bent 120 degrees geometry to one C(4), one N(2), and one H(5) atom. The C(6)-N(2) bond length is 1.26 Å. The C(6)-H(5) bond length is 0.93 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one Cd(1), one C(1), and one C(5) atom. In the second N site, N(2) is bonded in a distorted single-bond geometry to one C(6) and one N(2) atom. The N(2)-N(2) bond length is 1.41 Å. There are four 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(3) is bonded in a single-bond geometry to one C(3) atom. In the third H site, H(4) is bonded in a single-bond geometry to one C(5) atom. In the fourth H site, H(5) is bonded in a single-bond geometry to one C(6) atom. Cl(1) is bonded in a linear geometry to two equivalent Cd(1) atoms. Linkers: 5 [CH]([N][N][CH]c1cccnc1)c1cccnc1. Metal clusters: 2 [Cd].
