The luminescence hosts K3YF6 and K3GdF6 were obtained in a single-crystal form. Their crystal structure was determined from single-crystal X-ray diffraction data. Both crystals adopt monoclinic system with space group P21/n , Z=2Z=2. Lattice parameters for K3YF6 are refined to the following values a=6.3376(13)Å, b=6.5435(13)Å, c=9.0390(18)Å, β=90.65(3)β=90.65(3) and for K3GdF6a=6.3759(13)Å, b=6.5922(13)Å, c=9.1200(18)Å, β=90.80(3)β=90.80(3). The vibrational analysis, IR and Raman spectroscopy at room temperature, was applied to these compounds in order to study the site symmetry of Y3+ and Gd3+ ions.
