Abstract

The new zeolite ERS-7 (EniRicerche-molecular-Sieve-7), which was synthesized within a narrow temperature and compositional range using N,N-dimethylpiperidinium as a structure directing agent, has a structure consisting of 17-sided (46546582) picnic-basket-shaped cages connected by 8-membered ring windows.
