This database provides structural information on all of the Zeolite Framework Types that have been approved by the Structure Commission of the International Zeolite Association (IZA-SC).
It is searchable and includes:
descriptions and drawings of each framework type
user-controlled animated displays of each framework type
crystallographic data and simulated powder diffraction patterns for representative materials
detailed instructions for building models
measured powder patterns from "Verified Syntheses" (2nd and 3rd edition)
29Si MAS NMR spectra for pure silica and aluminosilicate zeolites
31P MAS NMR spectra for pure aluminophosphate zeolites
framework chemical composition for all materials in the database
A separate database, designed to describe disordered zeolite structures more appropriately, has been created and integrated into this one under the tab Intergrowths.
If you run into any difficulties with the database or have any suggestions for improvements, please contact Christian Baerlocher.
|Latest news from the Structure Commission|
A new Database of Disordered Zeolite Structures has been created.
To access it, just click on the Intergrowths tab above.
This database is still being developed, so corrections, comments, suggestions and other feedback are most welcome.
|16-July-21||New framework type code approved: ANO and PTO|
|30-Sept-20||New tool: Check topology. Checks whether your structure has a new topology. For a known structure it will list the corresponding topological T-positions|
|24-Sept-20||New framework type code approved: PTT||31-Jul-20||31P MAS NMR spectra of 32 pure aluminophosphates have been added to the database.
|30-Mar-20||Framework chemical composition included for all materials in the database |
|26-Jun-19||First NMR added: |
29Si MAS NMR spectra of some pure silica zeolites have been added to the database.
|26-Apr-19||New framework type codes approved: AVE, SOV, PWN|
|20-Aug-18||New framework type codes approved: MRT, *PCS, POR, PWO, PWW, *UOE|
|15-May-18||New framework type codes approved: *CTH, SOR, *-SVY, YFI|
|11-Dec-17||New features added:
A subset of the measured powder patterns from "Verified Syntheses" book (3rd edition), published by the Synthesis Commission, are now included in the database (Powder Pattern tab). You can zoom in, rescale, add your own pattern and print the resulting plot as for the simulated patterns. Links to the recipes are also included for these phases.
|15-Aug-17|| Database now fully functional on mobile devices
Origin of names of Type Material and derivation of 3-letter code added to Type Material page
Search added for number of topologically distinct T-atoms (on Channel System search page)

|17-Mar-17||Fully revised version of the Database of Zeolite Structures launched|
|1-Oct-16||20 years of Zeolite Structures on the web (Learn more about the history of the database here)|
