Abstract

We will present the synthesis, structure and magnetic properties of a new quadruple-layered perovskite (CuCl)Ca ₂NaNb ₄O ₁₃. Through a topotactic ion-exchange reaction with CuCl ₂, the precursor RbCa ₂NaNb ₄O ₁₃ presumably having an incoherent octahederal tliting changes into (CuCl)Ca ₂NaNb ₄O ₁₃ with a 2a _p×2a _p×2c _p superstructure (tetragonal; a=7.73232(5) Å, c=39.2156(4) Å). The well-defined superstructure for the ion-exchanged product should be stabilized by the inserted CuCl ₄O ₂ octahedral layers that firmly connect with neighboring perovskite layers. Magnetic studies show the absence of long-range magnetic ordering down to 2 K despite strong in-plane interactions. Aleksandrov′s group theory and Rietveld refinement of synchrotron X-ray diffraction data suggest the structure to be of I4/mmm space group with in-phase tilting along the a and b axes, a two-tilt system (0).
