CuC6H8(N5O2)2 is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two CuC6H8(N5O2)2 clusters. Cu(1) is bonded in a square co-planar geometry to two equivalent N(1) and two equivalent O(2) atoms. Both Cu(1)-N(1) bond lengths are 1.98 Å. Both Cu(1)-O(2) bond lengths are 1.97 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(4), and one N(5) atom. The C(1)-N(1) bond length is 1.35 Å. The C(1)-N(4) bond length is 1.36 Å. The C(1)-N(5) bond length is 1.34 Å. In the second C site, C(2) is bonded in a distorted trigonal non-coplanar geometry to one N(4), one H(3), and one H(4) atom. The C(2)-N(4) bond length is 1.44 Å. The C(2)-H(3) bond length is 1.10 Å. The C(2)-H(4) bond length is 1.10 Å. In the third 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 1.29 Å. There are five inequivalent N sites. In the first N site, N(2) is bonded in a water-like geometry to one N(1) and one N(3) atom. The N(2)-N(1) bond length is 1.37 Å. The N(2)-N(3) bond length is 1.29 Å. In the second N site, N(3) is bonded in a water-like geometry to one N(2) and one N(4) atom. The N(3)-N(4) bond length is 1.37 Å. In the third N site, N(4) is bonded in a distorted trigonal planar geometry to one C(1), one C(2), and one N(3) atom. In the fourth N site, N(5) is bonded in a distorted trigonal planar geometry to one C(1), one H(1), and one H(2) atom. The N(5)-H(1) bond length is 1.03 Å. The N(5)-H(2) bond length is 1.01 Å. In the fifth N site, N(1) is bonded in a distorted trigonal planar geometry to one Cu(1), one C(1), and one N(2) atom. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one N(5) atom. In the second H site, H(2) is bonded in a single-bond geometry to one N(5) atom. In the third H site, H(3) is bonded in a single-bond geometry to one C(2) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one C(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one C(3) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Cu(1) and one C(3) atom.
