Ni2C5NH3O7(CH)3C3H2 is Indium-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of twelve 02329_fluka molecules; two 2,3-dimethyl-1,3-butadiene molecules; and two Ni2C5NH3O7 clusters. In each Ni2C5NH3O7 cluster, there are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded to one O(1), one O(3), one O(6), and two equivalent O(7) atoms to form NiO5 square pyramids that share  a cornercorner with one Ni(2)NO4 square pyramid,  an edgeedge with one Ni(2)NO4 square pyramid, and  an edgeedge with one Ni(1)O5 square pyramid. The Ni(1)-O(1) bond length is 2.08 Å. The Ni(1)-O(3) bond length is 2.12 Å. The Ni(1)-O(6) bond length is 2.02 Å. Both Ni(1)-O(7) bond lengths are 2.06 Å. In the second Ni site, Ni(2) is bonded to one N(1), one O(2), one O(3), one O(5), and one O(7) atom to form a mixture of edge and corner-sharing NiNO4 square pyramids. The Ni(2)-N(1) bond length is 2.06 Å. The Ni(2)-O(2) bond length is 2.11 Å. The Ni(2)-O(3) bond length is 2.12 Å. The Ni(2)-O(5) bond length is 2.06 Å. The Ni(2)-O(7) bond length is 2.04 Å. There are five inequivalent C sites. In the first C site, C(4) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. The C(4)-O(1) bond length is 1.25 Å. The C(4)-O(2) bond length is 1.26 Å. In the second C site, C(5) is bonded in a distorted bent 120 degrees geometry to one O(3) and one O(4) atom. The C(5)-O(3) bond length is 1.28 Å. The C(5)-O(4) bond length is 1.23 Å. In the third C site, C(7) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(5) atom. The C(7)-N(1) bond length is 1.30 Å. The C(7)-H(5) bond length is 0.93 Å. In the fourth C site, C(6) is bonded in a distorted bent 120 degrees geometry to one O(5) and one O(6) atom. The C(6)-O(5) bond length is 1.25 Å. The C(6)-O(6) bond length is 1.24 Å. In the fifth C site, C(11) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(8) atom. The C(11)-N(1) bond length is 1.28 Å. The C(11)-H(8) bond length is 0.93 Å. N(1) is bonded in a trigonal planar geometry to one Ni(2), one C(11), and one C(7) atom. There are three inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(7) atom. The H(1)-O(7) bond length is 0.85 Å. In the second H site, H(5) is bonded in a single-bond geometry to one C(7) atom. In the third H site, H(8) is bonded in a single-bond geometry to one C(11) atom. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Ni(1) and one C(4) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Ni(2) and one C(4) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Ni(1), one Ni(2), and one C(5) atom. In the fourth O site, O(4) is bonded in a single-bond geometry to one C(5) atom. In the fifth O site, O(5) is bonded in a bent 120 degrees geometry to one Ni(2) and one C(6) atom. In the sixth O site, O(6) is bonded in a distorted bent 120 degrees geometry to one Ni(1) and one C(6) atom. In the seventh O site, O(7) is bonded in a distorted single-bond geometry to one Ni(2), two equivalent Ni(1), and one H(1) atom.
