Abstract

Several REZnPnO phases of the ZrCuSiAs type (RE = rare earth element, Pn = P, As, Sb) were synthesized in X-ray-pure form in NaCl/KCl salt fluxes. The structure of PrZnSbO was refined from single-crystal diffractometer data: P4/nmm, a = 418.79(8), c = 946.7(5) pm, wR2 = 0.0349, 192 F(2) values, 12 parameters. The REZnPnO pnictide oxides were studied with respect to magnetic susceptibility, (121)Sb Mossbauer spectroscopy, and optical properties.
