The luminescence hosts K{sub 3}YF{sub 6} and K{sub 3}GdF{sub 6} 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 P2{sub 1}/n, Z=2. Lattice parameters for K{sub 3}YF{sub 6} are refined to the following values a=6.3376(13)A, b=6.5435(13)A, c=9.0390(18)A, {beta}=90.65(3) and for K{sub 3}GdF{sub 6}a=6.3759(13)A, b=6.5922(13)A, c=9.1200(18)A, {beta}=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 Y{sup 3+} and Gd{sup 3+} ions.
