The present invention addresses the problem of providing: a novel metal-organic structure in which a dicarboxylic acid having a terphenyl skeleton is used as an organic ligand; and a gas storage method using the metal-organic structure. A metal organic structure in which a carboxylate ion represented by formula (I) and a polyvalent metal ion are bonded. (In formula (I), R1 and R2 each independently represent a hydroxyl group, an unsubstituted or substituted C1-6 alkyl group, or the like, R10 and R11 each independently represent an unsubstituted or substituted C1-6 alkyl group, or the like, and R20 represents an unsubstituted or substituted C1-6 alkyl group, or the like. However, substituents on R1, R2, R3, R4, R5, R6, R7, R8, R10, R11, and R20 do not include a carboxyl group (COOH) and a carboxylate ion group (COO-). In addition, R10 and R11 are not methyl at the same time. ) 本发明的课题在于提供一种将具有三联苯骨架的二羧酸作为有机配体的新型金属有机结构体和使用其的气体储藏方法。一种金属有机结构体，其是式(I)所表示的羧酸根离子与多价金属离子键合而成的。(式(I)中，R1及R2各自独立地表示羟基、无取代的或具有取代基的C1～6烷基等，R10及
