Gianluigi, you can display any CIF file in ICSD using the search form eg http://icsd.ill.fr/icsd/index.php?action=Search&elements=cu+o+h&elementc=5 Click on the Demo option in the log-in box, and then on any of the "Struct.Formula". This ICSD interface was designed to display CIF files in the database, not your own CIF files, but I will see if I can implement that.
