The Inorganic Crystal Structure Database (ICSD) is a database of the crystal structures of inorganic substances, including pure elements, metals, minerals, and other purely inorganic substances. No organic or organometallic substances appear; data for these types of molecules can be found in the Cambridge Structural Database. There are currently over 156,000 entries in ICSD (http://www.fiz-karlsruhe.de/icsd_content.html?&L=tjslfmciqrkr).
How Do I Search?
How Do I Interpret My Results
The results will be presented as a list of substances that have published crystal structures. The default presentation for this list is the Brief View, which includes the substance's ICSD accession number, the HMS, the structural formula and type of crystal, and information about the document in which the structure was published. You will see a blue star beside every entry that is deemed to be high-quality data, and each entry ends in a little computer disk icon that you can click to download the .cif file.
Check the boxes beside any of the results that particularly interest you. In the left-most column, an option will open in the Navigation section to allow you to get a Detailed View of all the substances that you've checked. This gives you much more detailed information, including the ability to examine the individual bond lengths and angles in the unit cell.
