Co4C32N24H16Cl crystallizes in the cubic Fm-3c space group. Co(1) is bonded to two equivalent N(1), two equivalent N(2), and one Cl(1) atom to form corner-sharing CoN4Cl square pyramids. Both Co(1)-N(1) bond lengths are 2.06 Å. Both Co(1)-N(2) bond lengths are 2.07 Å. The Co(1)-Cl(1) bond length is 2.53 Å. There are four inequivalent C sites. In the first C site, C(2) is bonded in a distorted single-bond geometry to one C(3) and one N(3) atom. The C(2)-C(3) bond length is 1.48 Å. The C(2)-N(3) bond length is 1.35 Å. In the second 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 1.33 Å. The C(1)-H(1) bond length is 0.93 Å. In the third C site, C(3) is bonded in a trigonal planar geometry to one C(2) and two equivalent C(4) atoms. Both C(3)-C(4) bond lengths are 1.39 Å. In the fourth C site, C(4) is bonded in a single-bond geometry to two equivalent C(3) and one H(2) atom. The C(4)-H(2) bond length is 0.93 Å. There are three inequivalent N sites. In the first N site, N(1) is bonded in a distorted trigonal planar geometry to one Co(1), one C(1), and one N(2) atom. The N(1)-N(2) bond length is 1.35 Å. In the second N site, N(2) is bonded in a distorted trigonal planar geometry to one Co(1), one N(1), and one N(3) atom. The N(2)-N(3) bond length is 1.32 Å. In the third N site, N(3) is bonded in a water-like geometry to one C(2) and one N(2) atom. There are two inequivalent H sites. In the first H site, H(2) is bonded in a single-bond geometry to one C(4) atom. In the second H site, H(1) is bonded in a single-bond geometry to one C(1) atom. Cl(1) is bonded in a square co-planar geometry to four equivalent Co(1) atoms.
