Superconductivity in Ca(10)(Ir(4)As(8))(Fe(2)As(2))(5) with Square-Planar Coordination of Iridium
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 e...
