Colourless, diamond-shaped single crystals of Y 3 F[Si 3 O 10 ] (monoclinic, P2 1 /n; a = 730.38(5), b = 1112.47(8), c = 1037.14(7) pm, b = 97.235(6)ยฐ, Z = 4) with thalenite-type structure are obtained upon the reaction of YF 3 with Y 2 O 3 and SiO 2 (1 : 4 : 9 molar ratio) in evacuated silica tubes
