##STR00001##

in the formula (1), R.sup.1 to R.sup.5 each independently represent a hydrogen atom, an alkyl group having 1 to 5 carbon atoms, or a group containing a fluorine atom, M represents a metal atom, and “n” represents a valence of the metal atom represented by M, provided that at least one of R.sup.2, R.sup.3, and R.sup.4 represents the group containing a fluorine atom.

Metal-organic framework materials (MOFs) are highly porous entities comprising a multidentate organic ligand coordinated to multiple metal centers. MOFs having ambient condition stability may comprise a plurality of metal clusters comprising one or more M.sub.4O clusters (M is a metal), and a plurality of 4-pyrazolecarboxylate ligands coordinated to the plurality of metal clusters to define an at least partially crystalline network structure having a plurality of internal pores. The MOFs may have a Pa3 symmetry, which upon activation may convert into Fm3m symmetry. Methods for synthesizing the MOFs may comprise combining a metal source, such as a preformed metal cluster, with 4-pyrazolecarboxylic acid, and reacting the preformed metal cluster with the 4-pyrazolecarboxylic acid to form a MOF having an at least partially crystalline network structure with a plurality of internal pores defined therein and comprising a plurality of metal clusters coordinated to a multidentate organic ligand comprising 4-pyrazolecarboxylate.
