The present invention provides a metal-organic framework which can both adsorb water vapor in low relative humidity and reduce the magnitude of the humidity difference between the adsorption humidity and the desorption humidity.
A metal organic framework wherein the metal ion is an aluminum ion, a first ligand is an organic compound ion consisting of a first heterocycle having two carboxyl groups, and a heteroatom composing the first heterocycle is present on the minor angle side of the angle created by the two carboxyl groups, a second ligand is different than the first ligand, is an organic compound ion consisting of a second heterocycle having two carboxyl groups, and a heteroatom composing the second heterocycle is present on the major angle side of the angle create by the two carboxyl groups, and a third ligand is different than the first ligand and the second ligand, is an organic compound ion having two carboxyl groups, and the first ligand, second ligand, and third ligand are present in a specific ratio.
