Abstract

Metal organic framework compositions can have a face centered cubic structure.

First claim

What is claimed is:

1 . A metal-organic framework composition, comprising:
a plurality of hexanuclear clusters including one or more of a rare earth metal ion, wherein at least one hexanuclear cluster associates with twelve hexanuclear clusters to form a metal-organic framework.

2 . The composition of claim 1 , wherein the hexanuclear clusters are characterized by the formula [RE 6 (μ 3 -OH) 8 (O 2 C—) 6 N 4 C—) 6 N 4 —) 6 ].

3 . The composition of claim 1 , wherein the hexanuclear clusters are characterized by the formula [RE 6 (μ 3 -OH) 8 (O 2 C—) 12 ].

4 . The composition of claim 1 , wherein the rare earth metal ion comprises one or more of cerium, dysprosium, erbium, europium, gadolinium, holmium, lanthanum, lutetium, neodymium, praseodymium, promethium, samarium, scandium, terbium, thulium, ytterbium, and yttrium.

5 . The composition of claim 1 , wherein the hexanuclear clusters are associated by a bidentate ligand.

6 . The composition of claim 5 , wherein the bidentate ligand includes one or more of a carboxylate, tetrazolate, triazolate, and pyrazolate.

7 . The composition of claim 5 , wherein the bidentate ligand includes one or more of FTZB, TZB, FTZBP, FBPDC, and DFBPDC.

8 . The composition of claim 5 , wherein the bidentate ligand has two anionic binding groups.

9 . The composition of claim 8 , wherein the two anionic binding groups are the same.

10 . The composition of claim 8 , wherein the two anionic binding groups are different.

11 . The composition of claim 8 , wherein the two anionic binding groups are linked by one or more of an aromatic group or hydrophobic group.

12 . The composition of claim 1 , wherein the hexanuclear clusters associate to form a metal-organic framework with fcu topology.

13 . A metal-organic framework composition, comprising:
a plurality of hexanuclear clusters that associate to form a metal-organic framework, wherein each of the hexanuclear clusters include one or more of a rare earth metal ion.

14 . The composition of claim 13 , wherein each of the hexanuclear clusters include twelve sites for ligand attachment to other hexanuclear clusters.

15 . The composition of claim 13 , wherein the rare earth metal ion comprises one or more of cerium, dysprosium, erbium, europium, gadolinium, holmium, lanthanum, lutetium, neodymium, praseodymium, promethium, samarium, scandium, terbium, thulium, ytterbium, and yttrium.

16 . The composition of claim 13 , wherein a bidentate ligand associates the plurality of hexanuclear clusters.

17 . The composition of claim 16 , wherein the bidentate ligand includes one or more of a carboxylate, tetrazolate, triazolate, and pyrazolate.

18 . The composition of claim 16 , wherein the bidentate ligand includes one or more of FTZB, TZB, FTZBP, FBPDC, and DFBPDC.

19 . The composition of claim 13 , wherein the plurality of hexanuclear clusters associate to form a metal-organic framework with face-centered cubic topology.

20 . A metal-organic framework composition, comprising:
a hexanuclear cluster associated with twelve other hexanuclear clusters to form a metal-organic framework with fcu topology, wherein each of the hexanuclear clusters include one or more of a rare earth metal ion.
