Mg6C32H32O21(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 Mg6C32H32O21 clusters. In each Mg6C32H32O21 cluster, there are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a square pyramidal geometry to one O(3) and four equivalent O(1) atoms. The Mg(1)-O(3) bond length is 2.06 Å. All Mg(1)-O(1) bond lengths are 2.05 Å. In the second Mg site, Mg(2) is bonded in a distorted hexagonal planar geometry to two equivalent H(7), one O(3), one O(4), and two equivalent O(2) atoms. Both Mg(2)-H(7) bond lengths are 1.57 Å. The Mg(2)-O(3) bond length is 1.77 Å. The Mg(2)-O(4) bond length is 2.15 Å. Both Mg(2)-O(2) bond lengths are 2.08 Å. There are four inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one C(2), one O(1), and one O(2) atom. The C(1)-C(2) bond length is 1.51 Å. The C(1)-O(1) bond length is 1.22 Å. The C(1)-O(2) bond length is 1.26 Å. In the second C site, C(2) is bonded in a trigonal planar geometry to one C(1), one C(3), and one C(4) atom. The C(2)-C(3) bond length is 1.41 Å. The C(2)-C(4) bond length is 1.41 Å. In the third C site, C(3) is bonded in a distorted single-bond geometry to one C(2) and one H(1) atom. The C(3)-H(1) bond length is 0.93 Å. In the fourth C site, C(4) is bonded in a distorted single-bond geometry to one C(2) and one H(2) atom. The C(4)-H(2) bond length is 0.93 Å. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(3) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(4) atom. In the third H site, H(6) is bonded in a 3-coordinate geometry to one H(6), one H(7), and one O(5) atom. The H(6)-H(6) bond length is 0.54 Å. The H(6)-H(7) bond length is 0.64 Å. The H(6)-O(5) bond length is 0.85 Å. In the fourth H site, H(7) is bonded in a single-bond geometry to one Mg(2), one H(6), and one O(5) atom. The H(7)-O(5) bond length is 0.85 Å. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one Mg(1) and one C(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Mg(2) and one C(1) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to one Mg(1) and two equivalent Mg(2) atoms. In the fourth O site, O(4) is bonded in a square co-planar geometry to four equivalent Mg(2) atoms. In the fifth O site, O(5) is bonded in a 4-coordinate geometry to four equivalent H(6) and four equivalent H(7) atoms.
