Co6C32H16O21(C5H3)8 is Indium-derived structured and crystallizes in the cubic Im-3 space group. The structure is zero-dimensional and consists of sixteen 1,3,5-triisopropenyl benzene molecules and six Co6C32H16O21 clusters. In each Co6C32H16O21 cluster, there are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 5-coordinate geometry to one O(3), one O(4), one O(5), and two equivalent O(2) atoms. The Co(1)-O(3) bond length is 1.72 Å. The Co(1)-O(4) bond length is 2.06 Å. The Co(1)-O(5) bond length is 2.21 Å. Both Co(1)-O(2) bond lengths are 2.06 Å. In the second Co site, Co(2) is bonded in a square pyramidal geometry to one O(3) and four equivalent O(1) atoms. The Co(2)-O(3) bond length is 2.17 Å. All Co(2)-O(1) bond lengths are 2.08 Å. There are four inequivalent C sites. In the first C site, C(5) is bonded in a distorted single-bond geometry to one C(6) and one H(3) atom. The C(5)-C(6) bond length is 1.40 Å. The C(5)-H(3) bond length is 0.93 Å. In the second C site, C(6) is bonded in a trigonal planar geometry to one C(5), one C(7), and one C(9) atom. The C(6)-C(7) bond length is 1.37 Å. The C(6)-C(9) bond length is 1.50 Å. In the third C site, C(7) is bonded in a distorted single-bond geometry to one C(6) and one H(4) atom. The C(7)-H(4) bond length is 0.93 Å. In the fourth C site, C(9) is bonded in a distorted bent 120 degrees geometry to one C(6), one O(1), and one O(2) atom. The C(9)-O(1) bond length is 1.23 Å. The C(9)-O(2) bond length is 1.28 Å. There are two inequivalent H sites. In the first H site, H(3) is bonded in a single-bond geometry to one C(5) atom. In the second H site, H(4) is bonded in a single-bond geometry to one C(7) atom. There are five inequivalent O sites. In the first O site, O(5) is bonded in a square co-planar geometry to four equivalent Co(1) atoms. In the second O site, O(4) is bonded in a water-like geometry to two equivalent Co(1) atoms. In the third O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Co(2) and one C(9) atom. In the fourth O site, O(2) is bonded in a bent 120 degrees geometry to one Co(1) and one C(9) atom. In the fifth O site, O(3) is bonded in a trigonal planar geometry to one Co(2) and two equivalent Co(1) atoms. Linkers: 8 [O]C(=O)c1ccc(-c2cc(-c3ccc(C([O])=O)cc3)cc(-c3ccc(C([O])=O)cc3)c2)cc1.
