Fluoroplatinates(IV) of the Lanthanides LnF[PtF6] (Ln = Pr, Sm, Gd, Tb, Dy, Ho, Er)For the first time fluorides LnF[PtF6] (Ln = Pr, Sm, Gd, Tb, Dy, Ho, Er), all yellow have been obtained. From single crystal data they crystallize monoclinic, space group P21/n-C2h5 (No. 14), Z = 4, Pr: a = 1 125.77(19) pm, b = 559.04(7) pm, c = 910.27(17) pm, β = 107.29(1)°; Sm: a = 1 114.63(31) pm, b = 552.70(12) pm, c = 898.02(20) pm, β = 107.24(2)°; Gd: a = 1 112.12(15) pm, b = 551.22(7) pm, c = 891.99(11) pm, β = 107.09(1)°; Tb (Powder data): a = 1 108.88(20) pm, b = 552.71(9) pm, c = 889.56(16) pm, β = 107.30(1)°; Dy: a = 1 100.28(23) pm, b = 547.77(8) pm, c = 882.41(13) pm, β = 107.32(1); Ho: a = 1 099.11(16) pm, b = 546.16(7) pm, c = 879.45(15) pm, β = 107.34(1)°; Er: a = 1 095.10(16) pm, b = 544.82(10) pm, c = 874.85(14) pm, β = 107.37(1)°.
Notes:
Erstmals dargestellt wurden Fluoride LnF[PtF6] (Ln = Pr, Sm, Gd, Tb, Dy, Ho, Er), alle gelb. Nach Einkristalluntersuchungen kristallisieren diese monoklin in der Raumgruppe P21/n-C2h5 (Nr. 14), Z = 4, Pr: a = 1 125,77(19) pm, b = 559,04(7) pm, c = 910,27(17) pm, β = 107,29(1)°; Sm: a = 1 114,63(31) pm, b = 552,70(12) pm, c = 898,02(20) pm, β = 107,24(2)°; Gd: a = 1 112,12(15) pm, b = 551,22(7) pm, c = 891,99(11) pm, β = 107,09(1)°; Tb (Pulverdaten): a = 1 108,88(20) pm, b = 552,71(9) pm, c = 889,56(16) pm, β = 107,30(1)°; Dy: 1 100,28(23) pm, b = 547,77(8) pm, c = 882,41(13) pm, β = 107,32(1)°; Ho: a = 1 099,11(16) pm, b = 546,16(7) pm, c = 879,45(15) pm, β = 107,34(1)°; Er: a = 1 095,10(16) pm, b = 544,82(10) pm, c = 874,85(14) pm, β = 107,37(1)°. Im Gegensatz zu älteren Befunden liegt die Raumgruppe P21/n-C2h5 (Nr. 14) mit einem verdoppelten Zellvolumen vor.
