摘要

α-Y2B4O9 was synthesized in a high-pressure/high-temperature experiment at 12.3 GPa/1020°C. The crystal structure has been determined via single-crystal X-ray diffraction. α-Y2B4O9 is isotypic to the lanthanide borates α-Ln2B4O9 (Ln=Sm–Ho) and crystallizes in the monoclinic space group C2/c (no. 15) with the following lattice parameters: a=25.084(2), b=4.3913(2), c=24.726(2) ?, and β=99.97(1)°. The compound was further characterized via X-ray powder diffraction as well as IR and Raman spectroscopy.
