CrystalMaker ships with a built-in library of over 1000 crystal and molecular structures. This is far more than a mere "database", providing rich metadata, notes, chemical formulae, rotatable previews - and a powerful search command. Even better, you can add your own structures to the Library Browser interface, so you can keep track of your own structures as you work.
Many more phases are available online, both on this site, and via new, open-access databases.
Note that CrystalMaker also lets you create your own structures, by typing data directly into the program, via the Edit > Structure command. This is useful if you have access to published data in print, and wish to display the data graphically.
With these resources, CrystalMaker users should be able to find many if not all of the structures they require, without recourse to commercial (or quasi-commercial) databases.
We include well over 12,000 structures on this website - including silica polymorphs, sample protein structures, periodic tables of the elements (showing how atomic/ionic radii vary) - plus a wide range of alloys, intermetallics, pnictides and chalcogenides. Visit our library page for more information.
The American Mineralogist Crystal Structure Database contains all of the structures published in the American Mineralogist, the Canadian Mineralogist and now the European Journal of Mineralogy. You can access these structures at http://www.minsocam.org/MSA/Crystal_Database.html.
Select one or more of the crystal structures and download them in CIF format (".cif"). Drop the CIF file onto the CrystalMaker application icon and the structure appears in the Graphics Window.
We would particularly like to recommend the Crystallography Open Database set up by Prof Armel Le Bail, but with widespread international support. The database contains over 48,000 entries, which can be freely downloaded in the ubiquitous CIF format.
Just drag-and-drop one or more CIF files onto the CrystalMaker application icon and the structures will be loaded automatically.
