High-pressure/high-temperature synthesis, single-crystal structure analysis, and spectroscopic data of γ-Eu(BO2)3 and γ-Gd(BO2)3
Orthorhombic crystals of the compounds γ-Eu(BO2)3 and γ-Gd(BO2)3 were obtained by high-pressure/high-temperature syntheses at 10.5 GPa and 1100 and 900 °C, respectively. The structures were solved by single-crystal X-ray diffraction methods. The two compounds crystallize with four formula units per cell in the space group Pca21 (no. 29) with the unit cell parameters a = 18.2729(7), b = 4.4076(2), c = 4.2505(1) Å (Ln = Eu), and a = 18.2591(6), b = 4.4055(1), c = 4.2477(1) Å (Ln = Gd). Their infrared spectra and the luminescence spectrum of γ-Eu(BO2)3 are discussed.
