CuH8(C2N)4(C2H)8 is Indium-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is zero-dimensional and consists of four hexa-1,5-diene-3-yne, 2,5-dimethyl- molecules and two CuH8(C2N)4 clusters. In each CuH8(C2N)4 cluster, Cu(1) is bonded in a square co-planar geometry to four equivalent N(1) atoms. All Cu(1)-N(1) bond lengths are 2.01 Å. C(2) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(2) atom. The C(2)-N(1) bond length is 1.31 Å. The C(2)-H(2) bond length is 0.95 Å. N(1) is bonded in a trigonal planar geometry to one Cu(1) and two equivalent C(2) atoms. H(2) is bonded in a single-bond geometry to one C(2) atom. Linkers: 2 C(#Cc1ccncc1)c1ccncc1. Metal clusters: 2 [Cu]. The MOF has largest included sphere 4.78 A, density 0.93 g/cm3, surface area 5263.79 m2/g, accessible volume 0.54 cm3/g
