ZnH6(CN2)4 crystallizes in the tetragonal P4_12_12 space group. Zn(1) is bonded in a tetrahedral geometry to two equivalent N(1) and two equivalent N(2) atoms. Both Zn(1)-N(1) bond lengths are 2.01 Å. Both Zn(1)-N(2) bond lengths are 1.92 Å. There are two 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 N(4) atom. The C(1)-N(1) bond length is 1.31 Å. The C(1)-N(2) bond length is 1.30 Å. The C(1)-N(4) bond length is 1.36 Å. In the second C site, C(2) is bonded in a trigonal planar geometry to one N(1), one N(3), and one H(1) atom. The C(2)-N(1) bond length is 1.37 Å. The C(2)-N(3) bond length is 1.30 Å. The C(2)-H(1) bond length is 0.93 Å. There are four inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one Zn(1), one C(1), and one C(2) atom. In the second N site, N(2) is bonded in a 2-coordinate geometry to one Zn(1), one C(1), and one N(3) atom. The N(2)-N(3) bond length is 1.42 Å. In the third N site, N(3) is bonded in a distorted water-like geometry to one C(2) and one N(2) atom. In the fourth N site, N(4) is bonded in a trigonal planar geometry to one C(1), one H(2), and one H(3) atom. The N(4)-H(2) bond length is 0.86 Å. The N(4)-H(3) bond length is 0.86 Å. There are three inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(2) atom. In the second H site, H(2) is bonded in a single-bond geometry to one N(4) atom. In the third H site, H(3) is bonded in a single-bond geometry to one N(4) atom. Linkers: 2 NC1=NN=C[N]1 ,6 NC1=[N]=CN=N1. Metal clusters: 4 [Zn].
