Cu3C12N9H13O7 is Indium-like structured and crystallizes in the cubic I-43m space group. The structure is zero-dimensional and consists of eight Cu3C12N9H13O7 clusters. Cu(1) is bonded in a rectangular see-saw-like geometry to two equivalent N(1), one O(2), and one O(3) atom. Both Cu(1)-N(1) bond lengths are 1.97 Å. The Cu(1)-O(2) bond length is 1.97 Å. The Cu(1)-O(3) bond length is 2.01 Å. There are three inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one N(1), one N(2), and one H(1) atom. The C(1)-N(1) bond length is 1.31 Å. The C(1)-N(2) bond length is 1.33 Å. The C(1)-H(1) bond length is 0.93 Å. In the second C site, C(3) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. The C(3)-O(1) bond length is 1.24 Å. The C(3)-O(2) bond length is 1.26 Å. In the third C site, C(2) is bonded in a 3-coordinate geometry to one N(2) and two equivalent H(2) atoms. The C(2)-N(2) bond length is 1.48 Å. Both C(2)-H(2) bond lengths are 0.96 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 3-coordinate geometry to one Cu(1), one C(1), and one N(1) atom. The N(1)-N(1) bond length is 1.38 Å. In the second N site, N(2) is bonded in a trigonal planar geometry to one C(2) and two equivalent C(1) atoms. There are three inequivalent H sites. In the first H site, H(3) is bonded in a single-bond geometry to one O(3) atom. The H(3)-O(3) bond length is 0.87 Å. In the second H site, H(2) is bonded in a single-bond geometry to one C(2) atom. In the third H site, H(1) is bonded in a single-bond geometry to one C(1) atom. There are three inequivalent O sites. In the first O site, O(3) is bonded in a single-bond geometry to three equivalent Cu(1) and one H(3) atom. In the second O site, O(1) is bonded in a single-bond geometry to one C(3) atom.
