CuH16(C5N2)4(CH2)4 crystallizes in the cubic I-43m space group. The structure consists of forty-eight 02329_fluka molecules inside a CuH16(C5N2)4 framework. In the CuH16(C5N2)4 framework, 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 trigonal planar geometry to one C(4), one C(5), and one N(2) atom. The C(1)-C(4) bond length is 1.51 Å. The C(1)-C(5) bond length is 1.41 Å. The C(1)-N(2) bond length is 1.31 Å. In the second C site, C(2) is bonded in a distorted trigonal planar geometry to one C(3), one C(6), and one N(1) atom. The C(2)-C(3) bond length is 1.49 Å. The C(2)-C(6) bond length is 1.41 Å. The C(2)-N(1) bond length is 1.30 Å. In the third C site, C(3) is bonded in a water-like geometry to one C(2), one H(1), and one H(2) atom. The C(3)-H(1) bond length is 0.96 Å. The C(3)-H(2) bond length is 0.96 Å. In the fourth C site, C(4) is bonded in a water-like geometry to one C(1), one H(3), and one H(4) atom. The C(4)-H(3) bond length is 0.96 Å. The C(4)-H(4) bond length is 0.96 Å. In the fifth C site, C(5) is bonded in a trigonal planar geometry to one C(6) and two equivalent C(1) atoms. The C(5)-C(6) bond length is 1.38 Å. In the sixth C site, C(6) is bonded in a trigonal planar geometry to one C(5) and two equivalent C(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted trigonal planar geometry to one Cu(1), one C(2), and one N(2) atom. The N(1)-N(2) bond length is 1.40 Å. In the second N site, N(2) is bonded in a distorted bent 120 degrees geometry to one C(1) and one N(1) atom. There are four inequivalent H sites.
