The scientific renown of the iridium oxides (iridates) is strictly related to the formation of the exotic phases of matter arising from the delicate balance between various interactions at play, electronic correlation, crystal field and spin-orbit coupling, in particular. The most prominent example is the so-called Jeff = ½ ground state for the Ir4+ ions (5d5 electronic configuration) in octahedral coordination; depending on the lattice featuring corner-, edge- or face-sharing octahedra, then, materials behave very differently. Here, we propose to investigate Na4IrO4, where Ir4+ ions are coordinated to only four oxygens on a square planar plaquette, resulting in a complete modification of the electronic and magnetic structure, which cannot be framed into the conventional Jeff = ½ picture. RIXS investigation will allow us to corroborate or defy recent theoretical calculations, including the prediction of a giant magnetic anisotropy for Na4IrO4.
