context_page_description: Samarium(II) iodide is an inorganic compound with the formula SmI₂. When employed as a solution for organic synthesis, it is known as Kagan's reagent. SmI₂ is a green solid and its solutions are green as well. It is a strong one-electron reducing agent that is used in organic synthesis.
context_section_description: In samarium(II) iodide, the metal centers are seven-coordinate with a face-capped octahedral geometry.
   
  In its ether adducts, samarium remains heptacoordinate with five ether and two terminal iodide ligands.
