During attempts to synthesize a high-pressure phase of KSr4(BO3)3 using pressures of up to 12 GPa, single crystals of the normal-pressure phase KSr4(BO3)3 with sufficient quality for single-crystal diffraction experiments could be obtained at 3 GPa and 1300 °C in a Walker-type multianvil apparatus. The single-crystal structure determination verified the published powder diffraction data of KSr4(BO3)3 revealing the non-centrosymmetric space group Ama2 with a = 1104.8(2), b = 1199.1(2), c = 688.8(2) pm and Z = 4. Additionally, IR- and Raman-spectroscopic investigations were performed on single crystals of the compound.
