Red single crystals of EU2OI2 were obtained from a reaction mixture of barium metal, EuI2, EU4OI6 and some NH4I in a tantalum tube at 780/500 degrees 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 {EU4O} tetrahedra connected via trans edges to infinite chains. The iodide ions surround and connect these chains to a three-dimensional structure.
