Cd(CO2)4(CH2)4 is Indium-derived structured and crystallizes in the orthorhombic Fddd space group. The structure is zero-dimensional and consists of thirty-two 02329_fluka molecules and eight Cd(CO2)4 clusters. In each Cd(CO2)4 cluster, Cd(1) is bonded in a distorted hexagonal bipyramidal geometry to four equivalent O(1) and four equivalent O(2) atoms. All Cd(1)-O(1) bond lengths are 2.35 Å. All Cd(1)-O(2) bond lengths are 2.51 Å. C(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. The C(1)-O(1) bond length is 1.27 Å. The C(1)-O(2) bond length is 1.25 Å. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted single-bond geometry to one Cd(1) and one C(1) atom. In the second O site, O(1) is bonded in a distorted L-shaped geometry to one Cd(1) and one C(1) atom. Linkers: 16 [O]C(=O)CCC([O])=O. Metal clusters: 8 O=[C]O[Cd]12(O[C]=O)(O[C]O1)O[C]O2. RCSR code: dia. The MOF has largest included sphere 4.02 A, density 1.40 g/cm3, surface area 4156.76 m2/g, accessible volume 0.29 cm3/g
