CuH20(C3N)8 is Indium-like structured and crystallizes in the tetragonal P4_2/n space group. The structure is zero-dimensional and consists of two CuH20(C3N)8 clusters. Cu(1) is bonded in a tetrahedral geometry to four equivalent N(1) atoms. All Cu(1)-N(1) bond lengths are 2.03 Å. There are six inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(1) atom. The C(1)-N(1) bond length is 1.33 Å. The C(1)-H(1) bond length is 0.93 Å. In the second C site, C(2) is bonded in a distorted single-bond geometry to one C(3) and one H(2) atom. The C(2)-C(3) bond length is 1.34 Å. The C(2)-H(2) bond length is 0.93 Å. In the third C site, C(3) is bonded in a trigonal planar geometry to one C(2), one C(4), and one C(6) atom. The C(3)-C(4) bond length is 1.38 Å. The C(3)-C(6) bond length is 1.46 Å. In the fourth C site, C(4) is bonded in a distorted single-bond geometry to one C(3), one C(5), and one H(3) atom. The C(4)-C(5) bond length is 1.35 Å. The C(4)-H(3) bond length is 0.93 Å. In the fifth C site, C(5) is bonded in a distorted trigonal planar geometry to one C(4), one N(1), and one H(4) atom. The C(5)-N(1) bond length is 1.33 Å. The C(5)-H(4) bond length is 0.93 Å. In the sixth C site, C(6) is bonded in a distorted bent 120 degrees geometry to one C(3), one N(2), and one H(5) atom. The C(6)-N(2) bond length is 1.27 Å. The C(6)-H(5) bond length is 0.93 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one Cu(1), one C(1), and one C(5) atom. In the second N site, N(2) is bonded in a distorted single-bond geometry to one C(6) atom. There are five inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. 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(3) is bonded in a single-bond geometry to one C(4) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one C(5) atom. In the fifth H site, H(5) is bonded in a single-bond geometry to one C(6) atom. Linkers: 6 [CH]([N][N][CH]c1ccncc1)c1ccncc1. Metal clusters: 2 [Cu].
