AgCO2CH2 crystallizes in the orthorhombic Fddd space group. The structure consists of thirty-two 02329_fluka molecules inside a AgCO2 framework. In the AgCO2 framework, there are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. Both Ag(1)-O(1) bond lengths are 2.21 Å. Both Ag(1)-O(2) bond lengths are 2.55 Å. In the second Ag site, Ag(2) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. Both Ag(2)-O(1) bond lengths are 2.69 Å. Both Ag(2)-O(2) bond lengths are 2.19 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 1.28 Å. The C(1)-O(2) bond length is 1.28 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Ag(1), one Ag(2), and one C(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Ag(1), one Ag(2), and one C(1) atom. Linkers: 4 [O]C(=O)CCC([O])=O. Metal clusters: 8 [Ag]. The MOF has largest included sphere 1.61 A, density 3.85 g/cm3, surface area 1640.91 m2/g, accessible volume 0.03 cm3/g
