Crystal structures of over 500 common materials, elements, oxides, including:

• All elements
• Common oxides (SiO₂, CaO, etc.)
• Common halides (NaCl, etc.)
• Ice
• Zeolites
• Silicates, Carbonates, etc.
• Sulfides, Selenides, Tellurides (e.g., ZnS, etc.)
• Nitrides, Phosphides, Arsenides (e.g., GaAs, InP, etc.)

All files are available in the public domain, although most include citation information for the original structure.

All Zeolites are available from the International Zeolite Association (IZA) Structure Commission.

All other crystal structures are available through the Crystallographic Open Database.
