Summary:To provide an MOF that adsorbs water vapor at a low relative humidity while narrowing a range of a humidity difference between an adsorption humidity and a desorption humidity.SOLUTION: A metal organic structure has an aluminum ion Al3+, and a ligand coordinated to the aluminum ion Al3+. The ligand has an isophthalic acid ion as a first ligand, and a pyrazole-3,5-dicarboxylic acid ion as a second ligand. A molar ratio between the first ligand and the second ligand is [first ligand: second ligand=98-90:2-10].SELECTED DRAWING: Figure 1 【課題】低い相対湿度で水蒸気を吸着することと、吸着湿度と脱着湿度との湿度差の範囲を狭めることとを両立できるMOFを提供する。【解決手段】アルミニウムイオンAl3+と、前記アルミニウムイオンAl3+に配位している配位子からなる金属有機構造体であって、前記配位子が、第1の配位子としてのイソフタル酸イオンと、第2の配位子としてのピラゾール−3,5−ジカルボン酸イオンからなり、第1の配位子と第2の配位子のモル比が、第1の配位子:第2の配位子=98〜90:2〜10である、金属有機構造体。【選択図】図1
