Eu2Mn3C24(NO4)6(CH)18 crystallizes in the hexagonal P6/mcc space group. The structure consists of thirty-six 02329_fluka molecules inside a Eu2Mn3C24(NO4)6 framework. In the Eu2Mn3C24(NO4)6 framework, Eu(1) is bonded in a 9-coordinate geometry to three equivalent N(1) and six equivalent O(1) atoms. All Eu(1)-N(1) bond lengths are 2.50 Å. All Eu(1)-O(1) bond lengths are 2.45 Å. Mn(1) is bonded in a square co-planar geometry to four equivalent O(2) atoms. All Mn(1)-O(2) bond lengths are 2.12 Å. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted single-bond geometry to one N(1) atom. The C(1)-N(1) bond length is 1.33 Å. In the second C site, C(3) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. The C(3)-O(1) bond length is 1.27 Å. The C(3)-O(2) bond length is 1.24 Å. N(1) is bonded in a trigonal planar geometry to one Eu(1) and two equivalent C(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Eu(1) and one C(3) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Mn(1) and one C(3) atom. Linkers: 12 [O]C(=O)c1cccc(C([O])=O)n1. Metal clusters: 4 [Eu] ,6 [Mn]. The MOF has largest included sphere 7.22 A, density 1.53 g/cm3, surface area 3320.79 m2/g, accessible volume 0.27 cm3/g
