Abstract

The present invention relates to a porous metal-organic framework material comprising a bidentate organic compound bound by coordination to a metal ion, the metal ion being AlIII and the bidentate organic compound being 2,6-naphthalenedicarboxylate, wherein the X-ray diffractogram (XRD) of the framework material has a first reflection in the range from 6.5°<2Θ<7.5° and a second reflection in the range from 13.8°<2Θ<15.0°, the area of the first reflection being greatest in relation to the area of all reflections in the range from 2°<2Θ<70° and the area of the second reflection being second greatest, and the sum of the areas of the first and second reflections giving at least 50% in relation to the total area of all reflections in the range from 2°<2Θ<70°. The invention further relates to shaped bodies comprising such a framework material, processes for production of the framework material and also to the use of the framework material or of the proposed shaped body.
