Abstract

Na3MnF6, Mr = 237.90, monoclinic, P21/n, a = 5.4709 (9), b = 5.6830 (6), c = 8.0734 (12) Åβ = 88.964 (7) °, V= 250.97 (6) A 3, Z = 2, D x = 3.15 gcm-3, λ(Mo Kα) = 0.7107 A., μ = 27.6 cm-1, F(000) = 224, T = 293 K, R = 0.0152, wR = 0.0144 for 550 unique reflections [Fo > σ0.(Fo)]. The structure is isostructural with that of the cryolite Na3A1F6 and shows the weakest static Jahn-Teller distortion known to date for [MnF6]3- octahedra [d(Mn-F) axial 2.0176 (8), mean equatorial 1.880 (1) Å]. The ordering of the elongated octahedra is ferrodistortive. Of the Na ions, one third have octahedral and the remainder have bicapped trigonal prismatic eight coordination.
