Structural Redetermination and Photoluminescence Properties of the Niobium Oxyphosphate (NbO)PO.

The structure of (NbO)PO was solved and refined based on new single-crystal diffraction data revealing considerably more complexity than previously described. (NbO)PO crystallizes in the triclinic space group P1̅ with Z = 6. The lattice parameters determined at room temperature are a = 1066.

Synthesis and characterization of the new strontium borogermanate Sr(3-x/2)B(2-x)Ge(4+x)O₁₄ (x = 0.32).

The strontium borogermanate Sr(3-x/2)B(2-x)Ge(4+x)O14 (x = 0.32) was synthesized by high-temperature solid-state reaction of SrO, GeO2, and H3BO3 in a NaF/KF flux system using platinum crucibles. The structure determination revealed that Sr(3-x/2)B(2-x)Ge(4+x)O14 (x = 0.
