ZnH16(C2N)4 crystallizes in the cubic I-43m space group. Zn(1) is bonded in a tetrahedral geometry to four equivalent N(1) atoms. All Zn(1)-N(1) bond lengths are 1.99 Å. There are three inequivalent C sites. In the first C site, C(2) is bonded in a distorted trigonal planar geometry to one C(3) and two equivalent N(1) atoms. The C(2)-C(3) bond length is 1.49 Å. Both C(2)-N(1) bond lengths are 1.34 Å. In the second C site, C(3) is bonded in a 6-coordinate geometry to one C(2), two equivalent H(2), two equivalent H(3), and two equivalent H(4) atoms. Both C(3)-H(2) bond lengths are 0.96 Å. Both C(3)-H(3) bond lengths are 0.96 Å. Both C(3)-H(4) bond lengths are 0.96 Å. In the third 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 1.37 Å. The C(1)-H(1) bond length is 0.93 Å. N(1) is bonded in a trigonal planar geometry to one Zn(1), one C(1), and one C(2) atom. There are four 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 distorted single-bond geometry to one C(3) atom. In the third H site, H(3) is bonded in a single-bond geometry to one C(3) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one C(3) atom.
