where R.sup.21 is H or CH.sub.3, each R.sup.22 is a hydrocarbon group of C.sub.2-14 where a carbon is primary carbon, secondary carbon or tertiary carbon, Q is a single bond or a hydrocarbon group of C.sub.1-20 carbon atoms which may include an oxygen atom, a nitrogen atom, or a sulfur atom between carbon-carbon atoms of or at a bond terminal, and a halogen atom may be substituted for the hydrogen atom.

The object of the present invention addresses a problem of providing a novel hydrogen storage material containing a metal-organic framework that can effectively store hydrogen. Hydrogen can be effectively stored by use of a hydrogen storage material containing a metal-organic framework, the metal-organic framework comprising a carboxylate ion of formula (I) and a multivalent metal ion, wherein the carboxylate ion and the multivalent metal ion are bound to each other. (In formula (I), X is an unsubstituted or substituted C2-C20 alkyl group, an unsubstituted or substituted alkenyl group, an unsubstituted or substituted alkynyl group, an unsubstituted or substituted alkoxy group, an unsubstituted or substituted alkenyloxy group, an unsubstituted or substituted alkynyloxy group, a benzyloxy group, an unsubstituted or substituted alkylsulfanyl group, an unsubstituted or substituted alkenylsulfanyl group, an unsubstituted or substituted alkynylsulfanyl group, an unsubstituted or substituted alkylamino group, an unsubstituted or substituted dialkylamino group, an unsubstituted or substituted alkenylamino group, an unsubstituted or substituted dialkenylamino group, an unsubstituted or substituted alkynylamino group, an unsubstituted or substituted dialkynylamino group, a phenyl group, a sulfanyl group or an unsubstituted or substituted alkoxycarbonyl group.)
