In3C30N3H18O13(C2N2(CH2))6(C4NH2)3 is Indium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is zero-dimensional and consists of six C2N2(CH2) clusters, two C4NH2 clusters, and two In3C30N3H18O13 clusters. In each C2N2(CH2) cluster, there are two inequivalent C sites. In the first C site, C(8) is bonded in a 4-coordinate geometry to two equivalent C(2) and two equivalent N(1) atoms. Both C(8)-C(2) bond lengths are 1.39 Å. Both C(8)-N(1) bond lengths are 1.50 Å. In the second C site, C(2) is bonded in a distorted single-bond geometry to one C(8) and one H(2) atom. The C(2)-H(2) bond length is 0.93 Å. N(1) is bonded in a distorted bent 150 degrees geometry to one C(8) and one N(1) atom. The N(1)-N(1) bond length is 0.74 Å. H(2) is bonded in a single-bond geometry to one C(2) atom. In each C4NH2 cluster, there are three inequivalent C sites. In the first C site, C(6) is bonded in a distorted single-bond geometry to one C(3) and one H(4) atom. The C(6)-C(3) bond length is 1.36 Å. The C(6)-H(4) bond length is 0.93 Å. In the second C site, C(3) is bonded in a trigonal planar geometry to one C(4) and two equivalent C(6) atoms. The C(3)-C(4) bond length is 1.47 Å. In the third C site, C(4) is bonded in a trigonal planar geometry to one C(3) and two equivalent N(3) atoms. Both C(4)-N(3) bond lengths are 1.34 Å. N(3) is bonded in a bent 120 degrees geometry to two equivalent C(4) atoms. H(4) is bonded in a single-bond geometry to one C(6) atom. In each In3C30N3H18O13 cluster, In(1) is bonded to one N(2), one O(2), and four equivalent O(1) atoms to form corner-sharing InNO5 octahedra. The corner-sharing octahedral tilt angles are 60°. The In(1)-N(2) bond length is 2.16 Å. The In(1)-O(2) bond length is 2.02 Å. All In(1)-O(1) bond lengths are 2.13 Å. There are four inequivalent C sites. In the first C site, C(7) is bonded in a trigonal planar geometry to one C(9) and two equivalent C(1) atoms. The C(7)-C(9) bond length is 1.50 Å. Both C(7)-C(1) bond lengths are 1.39 Å. In the second C site, C(9) is bonded in a distorted bent 120 degrees geometry to one C(7) and two equivalent O(1) atoms. Both C(9)-O(1) bond lengths are 1.26 Å. In the third C site, C(5) is bonded in a distorted bent 120 degrees geometry to one N(2) and one H(3) atom. The C(5)-N(2) bond length is 1.35 Å. The C(5)-H(3) bond length is 0.93 Å. In the fourth C site, C(1) is bonded in a distorted single-bond geometry to one C(7) and one H(1) atom. The C(1)-H(1) bond length is 0.93 Å. N(2) is bonded in a trigonal planar geometry to one In(1) and two equivalent C(5) 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(3) is bonded in a single-bond geometry to one C(5) atom. There are two inequivalent O sites. In the first O site, O(2) is bonded in a trigonal planar geometry to three equivalent In(1) atoms. In the second O site, O(1) is bonded in a bent 120 degrees geometry to one In(1) and one C(9) atom.
