We report on the magnetization, resistivity and magnetoresistance (MR) measurements on polycrystalline Pr 0.5 Sr 0.5 MnO 3 . Quenching samples from 14003C to room temperature in water (sample I) or in air (sample II) leads to di4erent behaviors. Powder X-ray di4raction patterns for samples I and II

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
