AgH8(CN)2 crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of four AgH8(CN)2 clusters. Ag(1) is bonded in a linear geometry to two equivalent N(1) atoms. Both Ag(1)-N(1) bond lengths are 2.11 Å. C(1) is bonded in a 3-coordinate geometry to one N(1), one H(1), and one H(2) atom. The C(1)-N(1) bond length is 1.46 Å. The C(1)-H(1) bond length is 0.97 Å. The C(1)-H(2) bond length is 0.97 Å. N(1) is bonded in a 2-coordinate geometry to one Ag(1); one C(1); and two equivalent H(3,4) atoms. Both N(1)-H(3,4) bond lengths are 0.90 Å. There are three inequivalent H sites. In the first H site, H(2) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the third H site, H(3,4) is bonded in a single-bond geometry to one N(1) atom. Linkers: 4 NCCN. Metal clusters: 4 [Ag]. The MOF has largest included sphere 3.78 A, density 1.78 g/cm3, surface area 3323.62 m2/g, accessible volume 0.28 cm3/g
