The structural, electric and magnetic properties of PrSrCoO4 and Pr0.4Sr1.6CoO4 layered perovskites have been investigated. The Rietveld refinements of x-ray powder diffraction (XRD) patterns at room temperature indicate that the samples crystallize in K2NiF4-type structure with group symmetry I4/mmm. The specimens exhibit semi-conducting behavior.
