Synthesis, Structure, and Magnetic Properties of Compounds NaMIIZr2F11 (MII = Ti, V, Cu) and a Notice on NaPdZr2F11By synthesizing NaTiZr2F11 in form of red single crystals, it was possible to obtain a complex fluoride with Ti2+ for the first time. It crystallizes like the analogous greenish blue vanadium compound isotypic to AgPdZr2F11 [1] monoclinic, spacegroup C2/m-C2h3 (No. 12) with a = 918.0/911.5 pm, b = 682.6/675.7 pm, c = 780.8/776.6 pm, β = 116.2/116.2º and Z = 2.Colourless NaCuZr2F11 however crystallizes as a result of the Jahn-Teller distortion of Cu2+ triclinic (space group P1-Ci1 (No. 2), a = 552.7 pm, b = 568.2 pm, c = 768.0 pm, α = 111.0º, β = 97.4º, γ = 106.4º) and is - as expected - isotypic to NaAgZr2F11 [1].
Notes:
Mit der Synthese von rotem NaTiZr2F11 in Form von Einkristallen gelang es erstmals, Ti2+ in ein komplexes Fluorid einzubauen. Es kristallisiert wie die entsprechende blaugrüne Vanadiumverbindung NaVZr2F11 isotyp zu AgPdZr2F11 [1] monoklin, R.G. C2/m-C2h3 (Nr. 12) mit a = 918,0 bzw. 911,5 pm, b = 682,6 bzw. 675,7 pm, c = 780,8 bzw. 776,6 pm, β = 116,2º bzw. 116,2º und Z = 2.Farbloses NaCuZr2F11 hingegen gehört mit der Jahn-Teller-Verzerrung um Cu2+ triklin (Raumgruppe P1-Ci1 (Nr. 2), a = 552,7 pm, b = 568,2 pm, c = 768,0 pm, α = 111,0º, β = 97,4º und γ = 106,4º) erwartungsgemäß zum NaAgZr2F11-Typ [1].
