METAL COMPLEX, AND ADSORBENT, OCCLUSION MATERIAL AND SEPARATOR MATERIAL MADE FROM SAME

摘要

Disclosed is a metal complex having high adsorption properties, high gas occlusion properties and high gas separation properties. The general formula (I) is below; ?Chemical Formula 1?(in the formula, R1-R4 are as set forth in the description) The metal complex comprises a dicarboxylic acid compound (I) as represented by formula (I), at least one type of metal ion chosen from ions of the metals belonging to group 2 or groups 7-12 of the periodic table, and an organic ligand with bidentate ability in said metal ion, which is of the D8h point group, has a length in the longitudinal direction of at least 8.0 Å and less than 16.0 Å, and has 2-7 heteroatoms.
