Ni3C30N15H30O13(C4NH2)3 is Indium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is zero-dimensional and consists of two C4NH2 clusters and two Ni3C30N15H30O13 clusters. In each C4NH2 cluster, there are three inequivalent C sites. In the first C site, C(2) is bonded in a trigonal planar geometry to one C(3) and two equivalent N(3) atoms. The C(2)-C(3) bond length is 1.50 Å. Both C(2)-N(3) bond lengths are 1.33 Å. In the second C site, C(3) is bonded in a trigonal planar geometry to one C(2) and two equivalent C(6) atoms. Both C(3)-C(6) bond lengths are 1.36 Å. In the third C site, C(6) is bonded in a distorted single-bond geometry to one C(3) and one H(3) atom. The C(6)-H(3) bond length is 0.93 Å. N(3) is bonded in a bent 120 degrees geometry to two equivalent C(2) atoms. H(3) is bonded in a single-bond geometry to one C(6) atom. In each Ni3C30N15H30O13 cluster, Ni(1) is bonded to one N(2), one O(2), and four equivalent O(1) atoms to form corner-sharing NiNO5 octahedra. The corner-sharing octahedral tilt angles are 60°. The Ni(1)-N(2) bond length is 2.10 Å. The Ni(1)-O(2) bond length is 1.99 Å. All Ni(1)-O(1) bond lengths are 2.04 Å. There are four inequivalent C sites. In the first C site, C(7) is bonded in a distorted bent 120 degrees geometry to one N(2) and one H(4) atom. The C(7)-N(2) bond length is 1.34 Å. The C(7)-H(4) bond length is 0.93 Å. In the second C site, C(1) is bonded in a distorted single-bond geometry to one C(5) and one N(1) atom. The C(1)-C(5) bond length is 1.37 Å. The C(1)-N(1) bond length is 1.39 Å. In the third C site, C(4) is bonded in a bent 120 degrees geometry to one C(5) and two equivalent O(1) atoms. The C(4)-C(5) bond length is 1.49 Å. Both C(4)-O(1) bond lengths are 1.24 Å. In the fourth C site, C(5) is bonded in a trigonal planar geometry to one C(4) and two equivalent C(1) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted trigonal planar geometry to one C(1), one H(1), and one H(2) atom. The N(1)-H(1) bond length is 0.86 Å. The N(1)-H(2) bond length is 0.86 Å. In the second N site, N(2) is bonded in a trigonal planar geometry to one Ni(1) and two equivalent C(7) atoms. There are three inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one N(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one N(1) atom. In the third H site, H(4) is bonded in a single-bond geometry to one C(7) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one Ni(1) and one C(4) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to three equivalent Ni(1) atoms. Linkers: 4 n1ccc(cc1)C1=NC(=[N]=C([N]1)c1ccncc1)c1ccncc1 ,6 Nc1c(N)c(C([O])=O)c(N)c(N)c1C([O])=O.
