The great diversity offered by mixed frameworks phosphates, which structures result from the assembly of different coordination polyhedra, explains the important place these materials occupy in numerous application fields (environment, electrochemistry, non linear optics, etc). Among these compounds, transition element phosphates, actinide phosphates and trivalent elements phosphates are especially studied in the CRISMAT laboratory owing to their potential applications as catalytic materials or as nuclear waste matrices. These phosphates are synthesized using hydrothermal methods or solid state reactions and their structures are determined from single crystal XRD. Relationships existing either between synthesis parameters and structures, or between structure and properties, have been outlined. Some examples will be pointed out to illustrate the richness of these phosphates crystal chemistry.
