PROPOSED SYNTHETIC ZEOLITE ECR-1 STRUCTURE GIVES A NEW ZEOLITE FRAMEWORK TOPOLOGY

In this paper, the authors propose a structure for the recently synthesized zeolite phase ECR-1. The proposed model is an intimate twin of the mordenite and mazzite structures constructed by interposing layers of mordenite-like sheets between layers of mazzite-like cages. Although there is an ambiguity between two ways the layers are interconnected, this layer-twin model explains the results of sorption and crystallization experiments, the spectroscopic data, X-ray and electron diffraction, and high-resolution transmission electron microscopy lattice imaging results.
