摘要
Yellow single crystals of Eu4OI6 were grown from fluxes in Ta ampoules and structurally characterized by X-ray diffraction. Eu4OI6 crystallizes in a hexagonal system and is isotypic with the corresponding chloride and bromide compounds. The O atom and one Eu atom lie on sites with 3m symmetry; the other Eu atom and the two unique I atoms are at sites with m symmetry. The structure is characterized by O-centered tetrahedra of divalent europium cations [Eu-O = 2.391 (15) and 2.416 (5) Angstrom, and mean Eu-Eu = 3.94 Angstrom] and hexagonal channels along [001] filled with iodide anions.
