Crystallographic Information
- American Mineralogist Crystal Structure Database
- Crystal structure database that includes every structure published in the American Mineralogist, The Canadian Mineralogist, and the European Journal of Mineralogy.
- ASM Alloy Phase Diagrams
- More than 28,000 binary and ternary phase diagrams and associated phase and crystal data for more than 6200 systems.
- Bilbao Crystallographic Server
- Free crystallographic programs and databases from the Materials Laboratory at the University of the Basque Country, Spain.
- Cambridge Crystallographic Data Centre
- The CCDC is home to the Cambridge Structural Database, a key repository for organic and organometallic crystal data. (UT does not site-license the CSD, but you can ask in the library about available access.) The CCDC site also has demos, tutorials, free software, and many links of interest to crystallographers.
- Crystal Lattice Structures
- 3D lattice structures of common crystals. Contains links to 254 structures in 90 of the 230 space groups. (U.S. Naval Research Laboratory)
- Crystallography Open Database
- Searchable open-access repository of crystal data, with CIF format output.
- CRYSTMET
- Commercial repository of data for metals, alloys, intermetallics, minerals. (UT does not license.)
- Inorganic Crystal Structure Database
- Information about the primary repository for data on inorganic and intermetallic structures. (UT does not license the ICSD.)
- International Centre for Diffraction Data
- ICDD is a non-profit scientific organization dedicated to collecting, editing, publishing, and distributing powder diffraction data for the identification of crystalline materials. Some free content, including Advances in X-Ray Analysis (1996-2004). ICDD publishes the Powder Diffraction File (PDF), part of which is available in print. (UT does not site-license the electronic PDF, but you can ask in the library about available access.)
- International Tables for Crystallography
-
The definitive reference work that provides "articles and tables of data relevant to crystallographic research and to applications of crystallographic methods in all sciences concerned with the structure and properties of materials. Emphasis is given to symmetry, diffraction methods and techniques of crystal structure determination, and the physical and chemical properties of crystals. Each volume also contains discussions of theory, practical explanations and examples, all of which are useful for teaching." Content is available both in interlinked HTML format and PDF.
- Mineralogy Database
- Contains 4,442 individual mineral species descriptions and an image library, arranged by crystal form, XRPD, element composition, Dana and Strunz classifications, etc.
- Protein Data Bank
-
Repository for the processing and distribution of 3-D structure data of biological macromolecules determined by X-ray crystallography and NMR. The Research Collaboratory for Structural Bioinformatics is a non-profit collaboration between Rutgers, SDSC and NIST.
- Reciprocal Net
-
An expansion of the Indiana University Molecular Structure Center's Crystal Data Server, designed to assist researchers who utilize crystallographic data. Searchable and browsable repository database of crystal data on common compounds.
- Zeolite Structure Database
- The database of the Structure Commission of the International Zeolite Association provides structural information on all zeolite structure types. This includes crystallographic data and drawings for all zeolite framework types, simulated powder patterns for representative materials and relevant references.
