Description
The results of a combined infrared and Raman-spectroscopic analysis of the compounds [N(C2H5)4]3[Ln(III)(NCO)6](Ln = Yb, Lu) confirms the assumption that the central ion Ln3+ is octahedrally surrounded by six linear isocyanate ligands. The recently determined temperature dependence of the magnetic susceptibility of the Yb-complex in the range 1.0 < T < 300.2 K is compatible with the crystal field (=CF) splitting pattern: 0 = E(tau6) < E(tau8) < E(tau7) < E(tau'8) < E(tau'7) and a spectroscopic splitting factor. (orig.)
Abstract (German)
Die Ergebnisse einer kombinierten Infrarot- und Raman-spektroskopischen Analyse der Verbindungen [N(C2H5)4]3[Ln(III)(NCO)6](Ln = Yb, Lu) bestaetigen die Annahme, dass das Ln3+-Zentralion oktaedrisch von sechs linearen Isocyanatliganden umgeben ist. Die in einer neueren Arbeit bestimmte Temperaturabhaengigkeit der magnetischen Suszeptibilitaet des Yb-Komplexes im Bereich 1,0 < T < 300,2 K ist mit dem KF-Aufspaltungsmuster 0 = E(tau6) < E(tau8) < E(tau7) < E(tau'8) < E(tau'7) und einem spektroskopischen Aufspaltungsfaktor kompatibel.
