CdC4 is diamond structured and crystallizes in the cubic Fd-3m space group. The structure is zero-dimensional and consists of eight CdC4 clusters. Cd(1) is bonded in a tetrahedral geometry to four equivalent C(1) atoms. All Cd(1)-C(1) bond lengths are 2.17 Å. C(1) is bonded in a single-bond geometry to one Cd(1) atom. Linkers: 2 [C]#[C]. Metal clusters: . The MOF has largest included sphere 7.00 A, density 1.04 g/cm3, surface area 3361.62 m2/g, accessible volume 0.73 cm3/g
