Ni12C24N32H8O4Cl5 crystallizes in the cubic Pm-3m space group. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded to four equivalent N(1) and one Cl(1) atom to form corner-sharing NiN4Cl square pyramids. All Ni(1)-N(1) bond lengths are 2.03 Å. The Ni(1)-Cl(1) bond length is 2.48 Å. In the second Ni site, Ni(2) is bonded to two equivalent N(2), one O(1), and one Cl(2) atom to form edge-sharing NiN2ClO trigonal pyramids. Both Ni(2)-N(2) bond lengths are 2.07 Å. The Ni(2)-O(1) bond length is 1.99 Å. The Ni(2)-Cl(2) bond length is 2.43 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 1.39 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 1.47 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 trigonal planar geometry to one Ni(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 Ni(2), one C(1), and one N(1) atom. H(1) is bonded in a single-bond geometry to one C(3) atom. O(1) is bonded in a water-like geometry to two equivalent Ni(2) atoms. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a square co-planar geometry to four equivalent Ni(1) atoms. In the second Cl site, Cl(2) is bonded in an L-shaped geometry to two equivalent Ni(2) atoms.
