Zn(C3H3N2)2 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 1.98 Å. There are two inequivalent C sites. In the first C site, C(2) is bonded in a trigonal planar geometry to two equivalent N(1) and one H(2) atom. Both C(2)-N(1) bond lengths are 1.30 Å. The C(2)-H(2) bond length is 0.95 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 1.36 Å. The C(1)-H(1) bond length is 0.95 Å. N(1) is bonded in a distorted trigonal planar geometry to one Zn(1), one C(1), and one C(2) atom. There are two inequivalent H sites. In the first H site, H(2) is bonded in a single-bond geometry to one C(2) atom. In the second H site, H(1) is bonded in a single-bond geometry to one C(1) atom. Linkers: 12 C1=CN=C[N]1. Metal clusters: 6 [Zn]. The MOF has largest included sphere 11.74 A, density 0.83 g/cm3, surface area 4480.53 m2/g, accessible volume 0.89 cm3/g
