Structural analysis of interpenetrated methyl-modified MOF-5 and its gas-adsorption properties

The first example of an interpenetrated methyl-modified MOF-5 with the formula Zn 4 O(DMBDC) 3 (DMF) 2 , where DMBDC 2− is 2,5-dimethylbenzene-1,4-dicarboxylate and DMF is N , N -dimethylformamide (henceforth denoted as Me 2 MOF-5-int ), namely, poly[tris(μ 4 -2,5-dimethylbenzene-1,4-dicarboxylato)bis( N , N -dimethylformamide)-μ 4 -oxido-tetrazinc(II)], [Zn 4 (C 10 H 8 O 4 ) 3 O(C 3 H 7 NO) 2 ] n , has been obtained from a solvothermal...
