ICSD for WWW

Inorganic Crystal Structure Database


14 July 2011

This is the ILL's PHP-MySQL Inorganic Crystal Structure Database (ICSD-for-WWW). Unlicensed users only have access to a demonstration version, with a 3592 structure subset of the 140,116 inorganic structures in release 2011-1. To get started, just enter eg Y Ba2 Cu3 O in the elements box and click Search. (Click on the titles of the input boxes for help). If you are unfamiliar with ICSD-for-WWW, you may want to first look at some Pretty pictures of typical structures and a WWW Flash movie of all the things you can do (in an earlier version of ICSD).

Login or use the Demo (ICSD-for-WWW works with Win95 up to Mac-OSX & Linux, but not with old browsers).
Do not disable popups, cookies or javascript; a popup window is needed to login to the full database.
In the browser options, prefer to open new pages in a new window, not a new tab.


If you have problems, use a modern browser like Mozilla Firefox which is an excellent Netscape-like browser for most platforms (and only a 4.7 Mbyte download). With Internet Explorer, please include ICSD as a "trusted site" under "security".
