摘要：

Lithium yttrium tetrafluoride, LiYF4, M(r) = 171.8, tetragonal, I4(1)/a, a = 5.164 (1), c = 10.741 (2) angstrom, V = 286.5 (1) angstrom3, Z = 4, D(x) = 3.99 g cm-3, lambda(Mo Kalpha) = 0.7107 angstrom, mu = 204 cm-1, F(000) = 312, T = 295 K, R = 0.015 for 156 unique observed [F>4sigma(F)] reflections. The scheelite (CaWO4) structure is confirmed. Lithium is located at a 4BAR site with four equidistant fluoride ions. Yttrium is in an eightfold coordination typical for rare-earth ions.
