XRD (X-ray Diffraction)

X-ray diffraction provides information on the solid state compounds (powder, crystals, thin films…). This technique is used for determining the atomic and molecular structure of crystalline materials.


The main activity of the X-ray diffraction platform is the structural characterization of small molecules (organic molecules, coordination complexes, polyoxometalates, metal-organic frameworks

  • Qualitative analysis of powder : phase identification
  • Quantitative analysis of mixtures
  • Microstructurale study (size and strain parameters)
  • Pattern matching
  • Elucidation of crystal structures
  • Rietveld refinement

Single-crystals :
  • Selection and mounting
  • Determination of the unit cell parameters
  • Data collection & data treatment
  • Elucidation of the crystal structure
  • Refinement
  • Deposit of the CIF file in database

The X-ray diffraction platform is open to all research teams of our institute. Most diffraction devices are self-service after training by the manager. The platform also conducts studies for other external laboratories, public or private, and for companies. For any analysis request, please contact one of the manager.
