  • Ce(IO3)3 forms a three-dimensional network structure.
  • The structure consists of 1D chains of edge-sharing CeO9 polyhedra.
  • These chains are crosslinked by bridging iodate (IO3-) groups into 2D layers, further connected by long I-O contacts.
  • Three distinct coordination modes for the iodate groups were observed.
  • Normal I-O bond distances (1.806–1.846 Å) and O-I-O angles (89.9–100.9°) were determined.

    • Conclusions:

    • The crystal structure of Ce(IO3)3 is characterized by a complex 3D network architecture.
    • The diverse coordination modes of iodate ions contribute to the stability and structural complexity.
    • The findings provide fundamental insights into the structural chemistry of cerium iodates.
