X-ray crystallography revealed isomorphous structures for each of the lanthanide complexes where [Ln(NO3)3(H2O)3] is involved in hydrogen bonding interactions with 18-crown-6. The transition point where the structural motif changes from [Ln(18-crown-6)(NO3)3] (with the metal residing in the crown cavity) to [Ln(NO3)3(H2O)3] · 18-crown-6 has been identified as at the Nd/Sm interface. A similar investigation involving [Ln(tos)3(H2O)6] (tos = p-toluenesulfonate) and 18-crown-6 were resistant to crown incorporation. X-ray studies show extensive intra- and intermolecular hydrogen bonding is present. Abstractde Identifizierung der Grenze zwischen den Strukturmotiven von [Ln(18-Krone-6)(NO3)3] und [Ln(NO3)3(H2O)3] · 18-Krone-6 in der Lanthanoiden-Reihe Die Rekristallisierung von Ln(NO3)3 (Ln = Sm, Eu, Yb) aus wäßriger Lösung in Gegenwart von 18-Krone-6 führt zu [Ln(NO3)3(H2O)3] · 18-Krone-6. Röntgenstruktur-Analysen führen zu isomorphen Strukturen für alle drei Lanthanoid-Komplexe, in denen [Ln(NO3)3(H2O)3] mit 18-Krone-6 über Wasserstoffbrücken-Bindungen verknüpft ist. Der Übergang, an dem das Struktur-Motiv von [Ln(18-Krone-6)(NO3)3] (mit dem Metallatom in der Kavität des Kronenethers) zu [Ln(NO3)3(H2O)3] · 18-Krone-6 wechselt, wurde an der Schnittstelle Nd/Sm identifiziert. Eine analoge Untersuchung mit Ln(tos)3 · 6 H2O (tos = Toluol-4-sulfonat) und 18-Krone-6 ergab keine Anlagerung des Kronenethers. Röntgenographische Untersuchungen ergaben extensive intra- und intermolekulare Wasserstoffbrücken-Bindungen. Citing Literature Volume626, Issue12December, 2000Pages 2491-2497 RelatedInformation
