摘要：

Potassium yttrium tetrafluoride, KYF4, M(r) = 204.0, trigonal, P3(1), a = 14.060 (10), c = 10.103 (10) angstrom, V = 1729 (5) angstrom 3, Z = 18, D(x) = 3.49 g cm-3, lambda(Ag K-alpha) = 0.5594 angstrom, mu = 87.93 cm-1, F(000) = 753, room temperature, final R = 0.038 for 3045 independent reflections. KYF4 is a fluorite-related superstructure. Cations are distributed on three layers perpendicular to the c axis. In each layer, chains of YF12 groups formed by two F pentagonal bipyramids surrounding the Y atoms alternate with chains of F edge-shared distorted cubes surrounding the K atoms.
