CuH8(C2N)4 is alpha Po structured and crystallizes in the tetragonal P4/nbm space group. The structure is zero-dimensional and consists of two CuH8(C2N)4 clusters. Cu(1) is bonded in a square co-planar geometry to four equivalent N(1) atoms. All Cu(1)-N(1) bond lengths are 2.04 Å. 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 1.33 Å. The C(1)-H(1) bond length is 0.95 Å. N(1) is bonded in a trigonal planar geometry to one Cu(1) and two equivalent C(1) atoms. H(1) is bonded in a single-bond geometry to one C(1) atom. Linkers: 4 c1cnccn1. Metal clusters: 2 [Cu]. The MOF has largest included sphere 4.06 A, density 1.20 g/cm3, surface area 4410.85 m2/g, accessible volume 0.43 cm3/g
