We report the single crystal structure of LuNaPd6O8 grown from a sodium hydroxide flux. The utilization of a hydroxide flux has led to the preparation of the first ordered substitution of a lanthanide metal and an alkali metal on the A-site in a platinum group oxide and the first palladate to contain both a lanthanide metal and an alkali metal. The 1:1 ordered substitution of Lu3+ and Na+ in place of the commonly observed divalent cation leads to slabs of LuO8 and NaO8 cubes bridged together by PdO4 square planes. The compound crystallizes in the cubic space group Pm-3 (#200) with a=5.72500(10) Å and is structurally related to other cubic palladium oxides.
