ZnH4(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(3) is bonded in a single-bond geometry to one C(2) atom. The C(3)-C(2) bond length is 1.51 Å. In the second 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 1.38 Å. The C(1)-H(1) bond length is 0.93 Å. In the third C site, C(2) is bonded in a distorted trigonal planar geometry to one C(3) and two equivalent N(1) atoms. Both C(2)-N(1) bond lengths are 1.33 Å. N(1) is bonded in a trigonal planar geometry to one Zn(1), one C(1), and one C(2) atom. H(1) is bonded in a single-bond geometry to one C(1) atom. Linkers: 3 [C]C1=N[CH]C=N1 ,9 [C]C1=NC=C[N]1.
