| Sumario: | [EN] The new zeolite NUD-3 possesses a three-dimensional system of large pore channels that is topologically identical to those of ITQ-21 and PKU- 14. However, the three zeolites have distinctly different frameworks: a particular single 4-membered ring inside the denser portion of the zeolite is missing in PKU-14, disordered in ITQ-21 and fully ordered in NUD-3. We document these differences and use molecular simulations to unravel the mechanismbywhich a particular structure directing agent dication, 1,10-(1,2-phenylenebis(methylene))bis(3-methylimidazolium), is able to orient this inner ring. |
