Co12C24N32H8Cl5 crystallizes in the cubic Pm-3m space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to four equivalent N(1), one Cl(1), and one Cl(2) atom to form corner-sharing CoN4Cl2 octahedra. The corner-sharing octahedral tilt angles range from 0-90°. All Co(1)-N(1) bond lengths are 2.01 Å. The Co(1)-Cl(1) bond length is 2.34 Å. The Co(1)-Cl(2) bond length is 2.47 Å. In the second Co site, Co(2) is bonded in a 2-coordinate geometry to two equivalent N(2) and one Cl(1) atom. Both Co(2)-N(2) bond lengths are 2.01 Å. The Co(2)-Cl(1) bond length is 2.79 Å. There are three inequivalent C sites. In the first C site, C(3) is bonded in a single-bond geometry to two equivalent C(2) and one H(1) atom. Both C(3)-C(2) bond lengths are 1.37 Å. The C(3)-H(1) bond length is 0.93 Å. In the second C site, C(1) is bonded in a distorted water-like geometry to one C(2) and two equivalent N(2) atoms. The C(1)-C(2) bond length is 1.48 Å. Both C(1)-N(2) bond lengths are 1.34 Å. In the third C site, C(2) is bonded in a trigonal planar geometry to one C(1) and two equivalent C(3) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted single-bond geometry to one Co(1), one N(1), and one N(2) atom. The N(1)-N(1) bond length is 1.31 Å. The N(1)-N(2) bond length is 1.33 Å. In the second N site, N(2) is bonded in a 3-coordinate geometry to one Co(2), one C(1), and one N(1) atom. H(1) is bonded in a single-bond geometry to one C(3) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted single-bond geometry to one Co(1) and two equivalent Co(2) atoms. In the second Cl site, Cl(2) is bonded in a square co-planar geometry to four equivalent Co(1) atoms. Linkers: 8 c1c(C2=NN=N[N]2)cc(C2=NN=N[N]2)cc1C1=NN=N[N]1.
