| Abstract: | Er5(BO3)2F9 was synthesised under conditions of 3 GPa and 800 °C in a Walker‐type multianvil apparatus. The crystal structure was determined on the basis of single‐crystal X‐ray diffraction data, collected at room temperature. Er5(BO3)2F9 is isotypic to the recently synthesised Yb5(BO3)2F9 and crystallises in C2/c with the lattice parameters a = 2031.2(4) pm, b = 609.5(2) pm, c = 824.6(2) pm, and β = 100.29(3)°. The physical properties of RE5(BO3)2F9 (RE = Er, Yb) including high temperature behaviour and single crystal IR‐ / Raman spectroscopy were investigated. |
