LiCu2(CO3)4 crystallizes in the cubic Im-3m space group. Li(1) is bonded in a square co-planar geometry to four equivalent O(2) atoms. All Li(1)-O(2) bond lengths are 2.04 Å. Cu(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(1) atoms. All Cu(1)-O(1) bond lengths are 2.01 Å. C(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(1) atoms. The C(1)-O(2) bond length is 1.25 Å. Both C(1)-O(1) bond lengths are 1.30 Å. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted linear geometry to one Li(1) and one C(1) atom. In the second O site, O(1) is bonded in a water-like geometry to one Cu(1) and one C(1) atom. Linkers: 24 [O]C([O])=O. Metal clusters: 6 [Li] ,12 [Cu]. RCSR code: nju. The MOF has largest included sphere 9.47 A, density 1.27 g/cm3, surface area 3245.68 m2/g, accessible volume 0.45 cm3/g
