If you have the case of the isomorphic replacement of the atom Sr by Ce, the solid solution is formed, and using single crystal X-ray diffraction you can receive averaged distances for atoms Sr and Ce.

Bhange D.S.

If it is Powdered sample sample after Rietveld refinement of the obtained PXRD data you can get clue regarding the change in bond distances, provided that your XRD data should be of high quality to refine the atomic co-ordinates..
