Abstract

Single crystals of a new lanthanum potassium iridate, La_2.50K_1.50IrO₇, have been grown from a molten hydroxide flux. The structure, which is best described as resulting from the stacking of [AO₃] and mixed [A₂O] layers, is an member of the [AnB_n−1O_3n] family of perovskite-related oxides. La_2.50K_1.50IrO₇ is comprised of [La₂IrO₆] layers containing isolated [IrO₆] octahedra and these layers are separated by a [La_0.50K_1.50O]⁺ layer. The compound crystallizes in the space group with R3‾ space group with a = 5.7330(2) Å and c = 18.8328(9) Å.
