Database of Zeolite Structures

Welcome to the Database of Zeolite Structures
fully revised 2017

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
relevant references
detailed instructions for building models
descriptions of some families of disordered zeolite structures
measured powder patterns from "Verified Syntheses" (3rd edition)
29Si MAS NMR spectra for pure silica zeolites

If you run into any difficulties with the new database or have any suggestions for improvements, please contact Christian Baerlocher.
Latest news from the Structure Commission
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)
18-Jul-17 New framework type codes approved: EWS, -IFT, SWY
17-Mar-17 Fully revised version of the Database of Zeolite Structures launched
