摘要：

alpha-Calcium aluminium pentafluoride, M(r) = 162.05, monoclinic, C2/c, a = 8.712 (3), b = 6.317 (2), c = 7.349 (3) angstrom, beta = 115.04 (3)-degrees, V = 366.4 (4) angstrom3, Z = 4, D(x) = 2.94 Mg m-3, Mo K-alpha, lambda = 0.71073 angstrom, mu = 1.90 mm-1, F(000) = 312, room temperature, R = 0.020 for 1201 unique reflections. The sample was prepared by the chloride flux method. alpha-CaAlF5 is isotypic with CaCrF5 and is characterized by linked chains of AlF6 octahedra along the c axis between which Ca ions are inserted in pentagonal bipyramidal sites.
