Using both powder and single crystal neutron diffraction we have determined the room temperature structure of Pr 0.5 Sr 0.5 MnO 3 from melt-grown crystalline material. Contrary to previous measurements on polycrystalline samples we find the room temperature structure of Pr 0.5 Sr 0.5 MnO 3 is tetrag
