I agree with Doriana. NMR and XRD also share great relations in polymer and materials, such as solid-state NMR. A quick open-source examples here shows analysis of molecular sieves by both NMR and XRD, and property relations. https://doi.org/10.1021/j100133a023
The major difference between these technologies is that X-ray crystallography uses X-rays to determine the three-dimensional structure of a crystal, whereas NMR spectroscopy uses strong local magnetic fields to analyze the alignment of nuclei in an atom. However, it depends upon the materials you are going to check
