Abstract: The present disclosure provides a novel metal organic framework and a gas adsorbing material containing the metal organic framework. The metal organic framework in one aspect of the embodiment contains zinc (Zn) and at least one ligand selected from 4-methylimidazole (4-MeIm), imidazole (Im), and benzimidazole (BzIm). When a mole ratio of the 4-MeIm, Im, and BzIm is x:y:z (4-MeIm:Im:BzIm), the mole ratio x:y:z falls within a polygonal region (including on a boundary line) having the following vertices in a ternary composition diagram: A (1:0:0), B (0.608:0.392:0), C (0.407:0.441:0.152), D (0.278:0.496:0.226), E (0:0.613:0.387), F (0:0.388:0.612), G (0.221:0.277:0.502), H (0.455:0.117:0.428), and I (0.563:0:0.437).

Abstract: Provided are: a hydrocarbon adsorbent capable of adsorbing hydrocarbons, storing the adsorbed hydrocarbons up to a relatively high temperature, and desorbing the adsorbed and stored hydrocarbons at a relatively high temperature; an exhaust gas purifying catalyst composition using the same; an exhaust gas purifying catalyst; and a method for treating an exhaust gas. The hydrocarbon adsorbent comprises a zeolite having an MRT-type framework structure. The hydrocarbon adsorbent comprises a small-pore zeolite having a total desorption amount ZD1 of propylene desorbed at 50° C. or higher and lower than 300° C. being 3.5 mmol/g or less and a total desorption amount ZD2 of propylene desorbed at 300° C. or higher and 500° C. or lower being 0.5 mmol/g or more, per 1 g by mass of the small-pore zeolite, when adsorbing propylene at 50° C. and then heating from 50° C. to 500° C. under the condition of 10° C./min by a temperature-programmed desorption method.
