A few choices to consider:

1. Obtain a more complete database (perhaps PDF-4 from ICDD), or check other databases (perhaps COD database online)

2. Use a isostructural CIF file and modify the chemistry and lattice parameters to match your phase.

3. Index yourself using ITO, DICVOL, or other such indexing routines

Or, if you know the crystal structure and atomic positions, make your own using software like VESTA.

Are these free softawres?

VESTA is free software, yes. It can be downloaded from http://jp-minerals.org/vesta/en/download.html

you can use crystal maker, Diamond or VICKS also for Graphical crystal structure
