Tetrafluoroaurates(III) of Lanthanides MF[AuF4]2 (M = Tm, Yb, Lu).Tetrafluoroaurates(III) MF[AuF4]2 with M = Tm, Yb, Lu, all yellow, have been prepared for the first time. From single crystal data they crystallize orthorhombic, space group Pbcn-D2h14 (No. 60) with M = Tm: a = 1 102.92(8) pm, b = 904.38(8) pm, c = 2 164.46(23) pm; M = Yb: a = 1 100.98(12) pm, b = 902.23(8) pm, c = 2 157.36(23) pm; M = Lu: a = 1 099.28(18) pm, b = 900.70(15) pm, c = 2 151.50(46) pm.
Notes:
Neu dargestellt wurden gelbe Tetrafluoroaurate(III) der Lanthaniden MF[AuF4]2 mit M = Tm, Yb, Lu. Nach Einkristalluntersuchungen kristallisieren diese orthorhombisch in der Raumgruppe Pbcn-D2h14 (Nr. 60) mit Z = 12. Im Einzelnen wurden folgende Werte gefunden: Für M = Tm: a = 1 102,92(8) pm, b = 904,38(8) pm, c = 2 164,46(23) pm; M = Yb: a = 1 100,98(12) pm, b = 902,23(8) pm, c = 2 157,36(23) pm; M = Lu: a = 1 099,28(18) pm, b = 900,70(15) pm, c = 2 151,50(46) pm.
