Description
Summary:Pr 5 6 Al 11 5 6 O 19 , hexagonal, M w=740.69, P6 3/mmc, a=5.5582(2) A ̊ , c=21.999(1) A ̊ V-558.59(7) A ̊ 3 , Z=2, D x=4.10 g/cm 3. The structure has been refined by Rietveld analyses of neutron diffraction data recorded at room temperature. R p= 3.2%, R wp= 4.6%. The structure is of a defect magnetoplumbite type.
