Dear Nelson, You can also often find structures of interest in the American Mineralogist Crystal Structure database (http://rruff.geo.arizona.edu/AMS/amcsd.php). Both of your phases are listed numerous times in this data base, and you can download cif files. The database is freely available.

Prezado Nelson, You can find CIF files for both alumina and crocoite phases at the Crystallography Open Database (www.crystallography.net) looking for chemical elements. An excellent set of educational material on Rietveld refinement using GSAS+EXPGUI at the APS-11BM site ( http://www.aps.anl.gov
