Unprecedented Li<sup>+</sup> Exchange in an Anionic Metal–Organic Framework: Significantly Enhanced Gas Uptake Capacity Bo Liu Rui Zhang Chun-Yang Pan Hai-Long Jiang 10.1021/acs.inorgchem.7b00538.s002 https://acs.figshare.com/articles/dataset/Unprecedented_Li_sup_sup_Exchange_in_an_Anionic_Metal_Organic_Framework_Significantly_Enhanced_Gas_Uptake_Capacity/4818820 We herein report the first example of Li<sup>+</sup> exchanged with both the guest H<sub>2</sub>N­(Me)<sub>2</sub><sup>+</sup> cations located in the channels and the coordinated metal ions from an anionic metal–organic framework (MOF), leading to significant enhancement of the pore volume and gas sorption abilities of the exchanged MOF. Furthermore, both MOFs before and after Li<sup>+</sup> exchange show good selective adsorption for CO<sub>2</sub> over CH<sub>4</sub>. 2017-04-05 17:25:11 exchange show Unprecedented Li CH 4 metal ions pore volume gas sorption abilities CO 2 MOF Enhanced Gas Uptake Capacity
