High-Temperature Synthesis, Crystal Structure, and Properties of the New Sodium Rare-Earth Oxide Borates Na2Ln2(BO3)2O (Ln: Dy, Ho). — The title compounds are prepared by reaction of Ln2O3 (Ln: Dy, Ho) and H3BO3 in a Na2CO 3 flux at
900—950 °C and their structures are determined by powder XRD and single crystal
XRD for Na2Dy2(BO3)2O. The compounds crystallize in the monoclinic space group
P21/c (Z = 4) and are isotypic with the known phases Na2Ln2(BO3)2O (Ln:Y, La, Nd,
Sm—Gd, Er). Na2Dy2(BO3)2O is further characterized by DTA/TG measurements and
IR spectroscopy. — (HEYMANN, G.; BEYER, K.; HUPPERTZ*, H.; Z. Naturforsch., B: Chem. Sci. 50 (2004) 11-12, 1200-1208; Fachbereich Chem. Biochem.,
