Structure determination of as-made zeolite ITQ-52 by three-dimensional electron diffraction

The complete crystal structures of two as-made zeolites with the ITQ-52 structure (IFW framework type), where an alkylphosphonium and an aminophosphonium dications have been used as their respective organic structure-directing agents, have been solved by three-dimensional electron diffraction. Both organic cations have also been located within the 10-ring that connects the cavities of the IFW framework using the diffraction data. • Zeolite ITQ-52 can be obtained using different organic structure directing agents. • The location of the directing agent can be obtained using 3D electron diffraction. • Different diffraction techniques can be used depending on the samples. • Due to their resemblance, both organics locate in similar positions in the channels. • Changing the organic agent modifies the location of trivalent atoms in the zeolite.

Abstract

The complete crystal structures of two as-made zeolites with the ITQ-52 structure (IFW framework type), where an alkylphosphonium and an aminophosphonium dications have been used as their respective organic structure-directing agents, have been solved by three-dimensional electron diffraction. Both organic cations have also been located within the 10-ring that connects the cavities of the IFW framework using the diffraction data. • Zeolite ITQ-52 can be obtained using different organic structure directing agents. • The location of the directing agent can be obtained using 3D electron diffraction. • Different diffraction techniques can be used depending on the samples. • Due to their resemblance, both organics locate in similar positions in the channels. • Changing the organic agent modifies the location of trivalent atoms in the zeolite.
