Er5(BO3)2F9 was synthesized 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 synthesized Yb5(BO3)2F9 and crystallizes 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.
