Structure of metal-organic framework nanocrystals obtained from electron diffraction data by iterative phase retrieval

This is the authors' abstract. We don't add key points for this paper.

We demonstrate the iterative phase retrieval of DUT-8(Ni) metal-organic framework (MOF) nanocrystals using high-resolution electron diffraction data. The reconstructed images show contrast features associated with the crystal structure, revealing well-resolved metal-containing rows with interpretable shifts. These shifts correspond to previously reported crystal structure disorder within the MOF. Furthermore, electron diffraction patterns display modulations in the low-resolution region, indicative of the rectangular crystal shape. Based on these data, we also successfully reconstructed the crystal shape image, which closely matched the observed form of the crystal.
