La(CO2)3(CH)2 crystallizes in the orthorhombic Fddd space group. The structure consists of thirty-two 02329_fluka molecules inside a La(CO2)3 framework. In the La(CO2)3 framework, La(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(3), and four equivalent O(2) atoms. Both La(1)-O(1) bond lengths are 2.55 Å. Both La(1)-O(3) bond lengths are 2.61 Å. There are two shorter (2.50 Å) and two longer (2.84 Å) La(1)-O(2) bond lengths. There are two inequivalent C sites. In the first C site, C(3) is bonded in a distorted bent 120 degrees geometry to two equivalent O(1) atoms. Both C(3)-O(1) bond lengths are 1.25 Å. In the second C site, C(1) is bonded in a bent 120 degrees geometry to one O(2) and one O(3) atom. The C(1)-O(2) bond length is 1.26 Å. The C(1)-O(3) bond length is 1.26 Å. There are three inequivalent O sites. In the first O site, O(2) is bonded in a distorted single-bond geometry to two equivalent La(1) and one C(1) atom. In the second O site, O(1) is bonded in a distorted bent 120 degrees geometry to one La(1) and one C(3) atom. In the third O site, O(3) is bonded in a distorted water-like geometry to one La(1) and one C(1) atom. Linkers: 4 [O]C(=O)/C=C/C([O])=O ,2 [O]C(=O)C([O])=O. Metal clusters: 4 [La]. The MOF has largest included sphere 4.38 A, density 1.84 g/cm3, surface area 2730.12 m2/g, accessible volume 0.24 cm3/g
