(Cr3C36H24O13)2(CdH16(C4N)4)3 is Indium-derived structured and crystallizes in the hexagonal P6/mmm space group. The structure is zero-dimensional and consists of three CdH16(C4N)4 clusters and two Cr3C36H24O13 clusters. In each CdH16(C4N)4 cluster, Cd(1) is bonded in a square co-planar geometry to four equivalent N(1) atoms. All Cd(1)-N(1) bond lengths are 2.35 Å. There are two inequivalent C sites. In the first C site, C(3) is bonded in a 3-coordinate geometry to one C(2), one N(1), and one H(3) atom. The C(3)-C(2) bond length is 0.87 Å. The C(3)-N(1) bond length is 1.34 Å. The C(3)-H(3) bond length is 0.95 Å. In the second C site, C(2) is bonded in a 3-coordinate geometry to one C(3), one N(1), and one H(2) atom. The C(2)-N(1) bond length is 1.33 Å. The C(2)-H(2) bond length is 0.95 Å. N(1) is bonded in a 5-coordinate geometry to one Cd(1), two equivalent C(2), and two equivalent C(3) atoms. There are two inequivalent H sites. In the first H site, H(2) is bonded in a single-bond geometry to one C(2) atom. In the second H site, H(3) is bonded in a single-bond geometry to one C(3) atom. In each Cr3C36H24O13 cluster, Cr(1) is bonded to one O(2) and four equivalent O(1) atoms to form corner-sharing CrO5 square pyramids. The Cr(1)-O(2) bond length is 1.91 Å. All Cr(1)-O(1) bond lengths are 1.95 Å. There are four inequivalent C sites. In the first C site, C(1) is bonded in a 2-coordinate geometry to one C(4), one C(6), and one H(1) atom. The C(1)-C(4) bond length is 0.86 Å. The C(1)-C(6) bond length is 1.38 Å. The C(1)-H(1) bond length is 0.95 Å. In the second C site, C(5) is bonded in a distorted bent 120 degrees geometry to one C(6) and two equivalent O(1) atoms. The C(5)-C(6) bond length is 1.51 Å. Both C(5)-O(1) bond lengths are 1.25 Å. In the third C site, C(4) is bonded in a distorted water-like geometry to one C(1), one C(6), and one H(4) atom. The C(4)-C(6) bond length is 1.38 Å. The C(4)-H(4) bond length is 0.95 Å. In the fourth C site, C(6) is bonded in a 5-coordinate geometry to one C(5), two equivalent C(1), and two equivalent C(4) atoms. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(4) is bonded in a single-bond geometry to one C(4) atom. There are two inequivalent O sites. In the first O site, O(2) is bonded in a trigonal planar geometry to three equivalent Cr(1) atoms. In the second O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Cr(1) and one C(5) atom.
