SUMMARY

The discussion centers on locating the crystal structure of (Pb0.5Sn0.5)Te, which is identified as an XY crystal similar to NaCl and belongs to Space Group 225. Users are seeking information on the atomic layers closest to an X atom and their distances. The Materials Project is recommended as a resource for generating crystal structure data, although access issues were noted with other databases. The user also inquires about the availability of Wyckoff positions for (Pb0.5Sn0.5)Te.

PREREQUISITES
  • Understanding of crystal structures and space groups, specifically Space Group 225.
  • Familiarity with the Materials Project database and its functionalities.
  • Knowledge of Wyckoff positions in crystallography.
  • Basic concepts of XY crystals and their properties.
NEXT STEPS
  • Explore the Materials Project for detailed crystal structure data on (Pb0.5Sn0.5)Te.
  • Research the concept of Wyckoff positions and their significance in crystallography.
  • Investigate alternative open-access databases for crystallographic information.
  • Learn about the similarities and differences between (Pb0.5Sn0.5)Te and NaCl in terms of crystal structure.
USEFUL FOR

Researchers in materials science, crystallographers, and anyone involved in the study of crystal structures and their properties.

I would like to find the crystal structure of (Pb0.5Sn0.5)Te
I was told it is similar to NaCl basically an XY crystal
I think it is called Space Group: 225
I would like to know the first, second, third ...layer of atoms closest to a X atom...and perhaps their distance...

I found
http://materials.springer.com/isp/crystallographic/docs/sd_0380725
But it had some access control...
Is there any free-access open database available?
Thanks.

The Materials Project

You type in the crystal structure and it generates data

Thanks. I have registered and found NaCl.
Why there are two NaCl?
Furthermore, where can I find Wyckoff positions for this guy?

It does not seems to have (Pb0.5Sn0.5)Te?
