Abstract

original image

Ein Pentasil-Zeolith mit kleinen Poren (Nu-6(2)) und einer neuartigen Topologie entsteht beim Erhitzen des 4,4′-Bipyridin-haltigen Silicats Nu-6(1). Zur Bestimmung der Kristallstrukturen des Zeoliths und seiner Vorstufe wurden hochaufgelöste Röntgenpulverdiagramme, Direkte Methoden und Modellierung kombiniert. Nu-6(2) enthält Kanäle aus zwei unterschiedlichen Gruppen von Achterringen (siehe Bild).
