A new 3D porous Zn(II) compound [Zn 2 (L) 2 (C 2 O 4 )] n ⋅ 2(DMA) ( 1 , HL=4‐(4‐carboxyphenyl)‐2,2′ : 4′,4′′‐terpyridine, DMA=N, N’‐dimethylacetamide) was successfully synthesized with carboxyphenyl‐terpyridine ligand. X‐ray structural analysis revealed that compound 1 features a 2‐fold interpenetrated framework with (3,4)‐connected network topology. Despite interpenetration, compound 1 still contains high solvent‐accessible free volume owing to the existence of large 1D nanotube channels. Gas adsorption properties investigation of the activated 1 a confirms its high BET surface area, high CO 2 uptake capacity and excellent adsorption selectivity of CO 2 over CH 4 . Luminescent properties investigation indicate that compound 1 displays intense luminescence at room temperature.
