Abstract: The synthesis and the x-ray diffraction patter, magnetic susceptibility, and electrical resistivity of the orthorhombic phase of SrIr[O.sub.3] is described. The magnetic and electrical properties showed that the orthorhombic SrIr[O.sub.3] perovskite is paramagnetic below 170 K and is metallic above 44 K before a band type metal insulator transition appeared.
