Nigussie Alebachew Ayalew,

JCPDS is now the ICDD, and has been for some time. The software and the data are proprietary, which one of these databases cost a good amount of money. However, you can look at places like the crystallographic open database (COD) or American Mineralogist. SREC also provides a complete and upkept list of free crystallographic databases. These will allow you to search the composition you are looking for. The only caveat is that you need to check the structures that you use, with something like VESTA. I've included previous thread links as well as links to databases.

Good luck!

Thanks Alec Ladonis for the information.
