La2.50K1.50IrO7: An Example of an n=2 Member of the [AnBn−1O3n][A'2O] Family of Perovskite-Related Oxides
Single crystals of a new lanthanum potassium iridate, La2.50K1.50IrO7, 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 [AnBn−1O3n] family of perovskite-related oxides. La2.50K1.50IrO7 is comprised of [La2IrO6] layers containing isolated [IrO6] octahedra and these layers are separated by a [La0.50K1.50O]+ layer. The compound crystallizes in the space group with R3‾ space group with a = 5.7330(2) Å and c = 18.8328(9) Å.
