|Cambridge Structural Database [information]
|1 million entries: small-molecule organic and metal-organic crystal structures. Each entry includes crystal structure information, chemical/physical property data and associated journal article reference.
|Two options available: a web-based interface to CSD (WebCSD), and a downloadable suite of databases that includes CSD (CSD-Enterprise).
|Inorganic Crystal Structure Database
|200,000 inorganic crystal structures, with associated crystallographic information, property data, and journal article reference.
|Powder Diffraction File - PDF-4+ [information]
|461,000+ entries of inorganic diffraction data from crystals and powders.
|Please contact firstname.lastname@example.org for information on accessing PDF-4+
|Landolt-Börnstein / SpringerMaterials [information]
|Large collection of property data that includes some volumes of crystallographic data.
|SpringerMaterials is free to search, but we don't have a license for the database. We have the pre-2010 Landolt content online in Portico. See the Landolt/Portico handout for instructions.
|SciFinder-n and Reaxys [more]
|Key databases for chemical property data and associated journal article references.
|SciFinder requires a one-time registration, then logging in with each use.
