title = "Superconductivity in Ca10 (Ir4 As8) (Fe2 As2)5 with Square-Planar Coordination of Iridium",
abstract = "We report the unprecedented square-planar coordination of iridium in the iron iridium arsenide Ca 10 (Ir 4 As 8)(Fe 2 As 2) 5. This material experiences superconductivity at 16 K. X-ray photoemission spectroscopy and first-principles band calculation suggest Ir(II) oxidation state, which yields electrically conductive Ir 4 As 8 layers. Such metallic spacer layers are thought to enhance the interlayer coupling of Fe 2 As 2, in which superconductivity emerges, thus offering a way to control the superconducting transition temperature.",
