A Prototypical Zeolitic Lanthanide−Organic Framework with Nanotubular Structure

A novel three-dimensional (3D) microporous lanthanide−organic framework [Nd(2,5-pydc)(Ac)(H2O)]n·2nH2O (1) has been prepared under hydrothermal conditions. The results of an X-ray crystallographic analysis revealed that compound 1 has a 3D nanotubular structure. From the topological point of view, the intricate 3D framework of compound 1 can be specified by the Schläfli symbol (42638) as a zeolite ABW net. The H2 adsorption isotherm at 77 K shows an uptake of 132 cm3 g−1 at 1.0 atm.
