Cerium triiodate,Ce(IO3)3

The crystal structure of Ce(IO₃)₃ consists of one‐dimensional chains of edge‐sharing CeO₉ polyhedra which are crosslinked into two‐dimensional layers through bridging IO₃⁻ groups. The layers are held together via long I⋯O contacts, resulting in an extended three‐dimensional network. The I—O bond distances and O—I—O angles are normal, lying in the ranges 1.806 (4)–1.846 (4) Å and 89.9 (2)–100.9 (2)°, respectively. The three crystallographically independent iodate groups all show different coordination modes.
