Red single crystals of Eu 2 OI 2 were obtained from a reaction mixture of barium metal, EuI 2 , Eu 4 OI 6 and some NH 4 I in a tantalum tube at 780/500 °C. The crystal structure (orthorhombic, Imcb, Z = 4, a = 648.93(11), b = 742.85(13), c = 1307.1(3) pm, R1(all) = 0.0605) contains {Eu 4 O} tetrahedra connected via trans‐edges to infinite chains. The iodide ions surround and connect these chains to a three‐dimensional structure.
