ZnC8H4O4(C4NH2)2 is Indium-derived structured and crystallizes in the cubic P4_132 space group. The structure is zero-dimensional and consists of eight C4NH2 clusters and four ZnC8H4O4 clusters. In each C4NH2 cluster, there are four inequivalent C sites. In the first C site, C(1) is bonded in a distorted trigonal planar geometry to one C(6) and two equivalent N(1) atoms. The C(1)-C(6) bond length is 1.48 Å. There is one shorter (1.33 Å) and one longer (1.35 Å) C(1)-N(1) bond length. In the second C site, C(5) is bonded in a distorted single-bond geometry to one C(6) and one H(2) atom. The C(5)-C(6) bond length is 1.39 Å. The C(5)-H(2) bond length is 0.93 Å. In the third C site, C(6) is bonded in a trigonal planar geometry to one C(1), one C(5), and one C(7) atom. The C(6)-C(7) bond length is 1.40 Å. In the fourth C site, C(7) is bonded in a distorted single-bond geometry to one C(6) and one H(3) atom. The C(7)-H(3) bond length is 0.93 Å. N(1) is bonded in a bent 120 degrees geometry to two equivalent C(1) atoms. There are two inequivalent H sites. In the first H site, H(2) is bonded in a single-bond geometry to one C(5) atom. In the second H site, H(3) is bonded in a single-bond geometry to one C(7) atom. In each ZnC8H4O4 cluster, there are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in an octahedral geometry to six equivalent O(1) atoms. All Zn(1)-O(1) bond lengths are 2.07 Å. In the second Zn site, Zn(2) is bonded in a trigonal planar geometry to three equivalent O(2) atoms. All Zn(2)-O(2) bond lengths are 1.94 Å. There are four inequivalent C sites. In the first C site, C(2) is bonded in a distorted bent 120 degrees geometry to one C(3), one O(1), and one O(2) atom. The C(2)-C(3) bond length is 1.52 Å. The C(2)-O(1) bond length is 1.23 Å. The C(2)-O(2) bond length is 1.25 Å. In the second C site, C(3) is bonded in a trigonal planar geometry to one C(2), one C(4), and one C(8) atom. The C(3)-C(4) bond length is 1.36 Å. The C(3)-C(8) bond length is 1.39 Å. In the third C site, C(4) is bonded in a single-bond geometry to one C(3) and one H(1) atom. The C(4)-H(1) bond length is 0.93 Å. In the fourth C site, C(8) is bonded in a distorted single-bond geometry to one C(3) and one H(4) atom. The C(8)-H(4) bond length is 0.93 Å. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(4) atom. In the second H site, H(4) is bonded in a single-bond geometry to one C(8) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Zn(1) and one C(2) atom. In the second O site, O(2) is bonded in a single-bond geometry to one Zn(2) and one C(2) atom.
