New members of layered oxychloride perovskites with square planar coordination: Sr2MO2Cl2 (M = Mn, Ni) and Ba2PdO2Cl2.
New members of Ruddlesden-Popper type layered oxychloride compounds, Sr2MO2Cl2 (M = Mn, Ni) and Ba2PdO2Cl2, were synthesized under high-pressure conditions. Synchrotron XRD analysis revealed that all the phases adopt the tetragonal space group I4/mmm, where two-dimensional sheets composed of corner-sharing MO4/PdO4 squares were separated by rock-salt SrCl/BaCl layers.
