Summary:The structure of the new medium‐pore aluminophosphate molecular sieve PST‐6 is determined by the combined use of rotation electron diffraction tomography, synchrotron X‐ray powder diffraction, and computer modeling. PST‐6 was prepared by calcination of another new aluminophosphate material with an unknown structure synthesized using diethylamine as a structure‐directing agent, which is thought to contain bridging hydroxy groups. PST‐6 has 36 crystallographically distinct tetrahedral sites in the asymmetric unit and is thus crystallographically the most complex zeolitic structure ever solved. Strukturaufklärung: Das Aluminiumphosphat‐Molekularsieb PST‐6 (siehe Bild) enthält mittelgroße Poren und 36 kristallographisch unterschiedliche Tetraederzentren. Diese komplexeste bekannte Zeolithstruktur wurde durch Röntgenstreuung, Elektronenkristallographie und Computermodellierung bestimmt.
