Representative
Structures
Listed below are a number of different
zeolite structures in JPEG, virtual reality images (VRML), and SolidWorks formats. You can view the JPEG's easily with any browser, but the VRML files require a pluggin (see below) and the SolidWorks files would generally be downloaded and opened using SolidWorks software. Many other types of 3D modelling software support SolidWorks images as well. The VRML and SolidWorks files are 3D, while the JPEG's are 2D projections. These
are stacked tetrahedral images which are constructed by drawing tetrahedra around the tetrahedrally coordinated Si
or Al T-atoms, then adding spheres to depict the oxygen atoms which connect the Si and/or Al atoms. The actual diameter of the oxygen atoms is larger than depicted in these diagrams, but if they were drawn to actual dimensions, they would completely engulf the teterahedra, so we would lose the tetrahedral representation of the zeolites. Also, note that these images depict a small subset of the entire crytal which would extend in all dimensions.
[1] Thanks to Shane Stafford, an LSU student in ChE 4410 for these descriptions.
If you need a pluggin to view the VRML files, there are a couple of possibilities.
I like Cortona VRML Client:
http://www.parallelgraphics.com/
You can also try the Cosmo Player at: http://www.cai.com/cosmo/html/win95nt.htm
When installing this pluggin for Netscape or Internet Explorer in Windows,
choose "unsupported browser", then provide your path to your pluggin subdirectory.
If you have a particular interest in another zeolite phase, and you would
like me to include it, send me some e-mail, and I will consider adding
it to my list. However, you might also like to try drawing it yourself
by downloading STRUVIR,
which I used to draw the VRML images. SolidWorks files were made by importing the VRML images into Solidworks and editing the files.
