Two layered Co3+ oxychlorides, Sr3Co2O5Cl2 and Sr2CoO3Cl, with crystal structures related to the Ruddlesden-Popper type, are reported. Small crystals were grown by the self-flux method, and the structures were determined by single crystal X-ray diffraction. The layers are formed from CoO5Cl octahedra sharing corners, with the Cl in one of the apical positions, relatively distant from the Co such that the Co coordination polyhedra closely resemble CoO5 pyramids. The resulting CoO2 planes are highly buckled, with long in-plane Co-O bond lengths and short apical Co-O bondlengths.
