A novel 3D anionic metal–organic framework (MOF) of (Me 2 NH 2 ) 4 [Ni 8 (PTCA) 4 (μ 3 ‐OH) 4 (H 2 O) 4 ](DMF) 5 (H 2 O) 13 (H 4 PTCA=pyrene‐1,3,6,8‐tetracarboxylic acid) has been synthesized, in which Me 2 NH 2 + can be exchanged by Li + ions. The results of gas sorption measurements indicate that the desolvated MOFs both before and after Li + exchange show highly selective adsorption for CO 2 over CH 4 and N 2 gases, and the Li + ‐exchanged MOF exhibits enhanced CO 2 , CH 4 , and H 2 storage properties.
