Zn(CO2)3 crystallizes in the cubic I4_132 space group. Zn(1) is bonded in an octahedral geometry to six equivalent O(1) atoms. All Zn(1)-O(1) bond lengths are 2.10 Å. C(1) is bonded in a distorted bent 120 degrees geometry to two equivalent O(1) atoms. Both C(1)-O(1) bond lengths are 1.25 Å. O(1) is bonded in a bent 120 degrees geometry to one Zn(1) and one C(1) atom. Linkers: 12 [O]C(=O)C([O])=O. Metal clusters: 8 [Zn]. The MOF has largest included sphere 8.55 A, density 0.72 g/cm3, surface area 3510.87 m2/g, accessible volume 1.08 cm3/g
