Popis: For the compounds Na3Ln(PO4)2 (Ln = Tm, Yb, and Lu), Na3Ln(VO4)2 (Ln = Pr, Nd, and Sm), and Na3Ln(AsO4)2 (Ln = Sm, Eu, Gd, Y, Dy, Ho, Er, and Tm) at 60 kilobars and ambient temperature [obtained by quenching under pressure after preparation at high temperature (600-900°)], the crystallog. parameters were determined by x-ray diffraction. The crystal-structure types and variations of the formula volumes with Ln are discussed.
