Abstract

A previously unreported 1D iridate, K₃Ir₂O₆, has been grown by a flux method in O₂-rich environment, and its crystal structure was determined via single crystal structural analysis. It exhibits straight chains of face-sharing [IrO₆] octahedra, which are arranged along the crystallographic c axis, separated by nonmagnetic K ions. No magnetic transitions are observed during measured range, and the material is electrically insulating. Potentially interesting electronic behavior for K₃Ir₂O₆ is supported by electronic structure calculations. A structurally related material, K_16.3Ir₈O₃₀, which displays similar fundamental geometric units but in a different spatial arrangement - zigzag chains - based on edge and face sharing [IrO₆] octahedra, is also reported. Both materials are of interest for probing the properties of a 1D system with strong spin-orbit coupling.
