| Abstract: | Reported herein are two porous interpenetrated anionic Cd-carboxylate frameworks tuned by the length of organic linker. Shorter BDC linker and Cd(COO)4] building blocks in 1 generate a rare 4-connected 2-fold interpenetrating qtz network. But longer NDC linker in 2 produces a self-penetrated 8-connected bcu framework with Cd3(COO)8] SBUs. 1 and 2 both show selective CO2 adsorption and significantly, 2 exhibits the highest water vapor uptake performance (281 cm3·g? 1 at 298 K and P/P0 = 0.95) among all the interpenetrated MOFs. |
