Description / Table of Contents:
Newly prepared Na3NiF6 of violett-blue colour is monoclinic [a = 5.44; b = 5.67; c = 7.85 Å; β = 90.1°] and isotypic with cryolite as well as Na3CoF6 [a = 5.49; b = 5.71; c = 7.90 Å; β = 90.1°] and Na3FeF6 [a = 5.52; b = 5.73; c = 7.95 Å; β = 90.4°]. Na3NiF6 does not obey the Curie-Weiss Law; the dependence of the effective magnetic moments on temperature indicates an equilibrium between low-spin and high-spin form.
Notes:
Neu dargestellt wurde violettblaues Na3NiF6. das monoklin [a = 5,44; b = 5,67; c = 7,85 Å; β = 90,1°] im Kryolith-Typ kristallisiert, zu dem auch Na3CoF6 [a = 5,49; b = 5,71; c = 7,90 Å; β = 90,1°] und Na3FeF6 [a = 5,52; b = 5,73; c = 7,95 Å; β = 90,4°] gehören. Na3NiF6 befolgt das Curie-Weisssche Gesetzt nicht; die Temperaturabhängigkeit der effektiven magnetischen Momente weist auf ein Gleichgewicht zwischen low-spin- und high-spin-Form hin.
