Triangular Monometallic Cyanide Cluster Entrapped in Carbon Cage with Geometry-Dependent Molecular Magnetism

Abstract: Clusterfullerenes are capable of entrapping a variety of metal clusters within carbon cage, for which the entrapped metal cluster generally keeps its geometric structure (e.g., bond distance and angle) upon changing the isomeric structure of fullerene cage, and whether the properties of the entrapped metal cluster is geometry-dependent remains unclear. Herein we report an unusual triangular monometallic cluster entrapped in fullerene cage by isolating several novel terbium cyanide clusterfullerenes (TbNC@C) wi… Show more

“…Analogous to CNCFs, the metal cyanide clusterfullerenes (CYCFs) contained an encapsulated [CN] moiety, but this is bonded with only one metal atom . In 2017, Yang and co‐workers reported the first non‐IPR CYCF MNC@C 76 (M=Tb, Y), whereby the cage structure was elucidated by means of single‐crystal X‐ray diffraction to be C 2 v (19138)‐C 76 bearing a pair of DFPs (Figure b) .…”

“…[89,90] Analog zu CNCFs schließen Metallcyanidclusterfullerene (CYCFs) eine [CN]-Einheit ein, die jedoch mit nur einem Metallatom verbunden ist. [83,109,110] 2017 beschrieben Yang et al die ersten Nicht-IPR-CYCFs MNC@C 76 (M = Tb,Y ), wobei die Käfigstruktur mittels Einkristall-Rçntgenbeugung als C 2v (19138)-C 76 mit einem DFP-Paar aufgeklärt wurde (Abbildung 7b). [30] Interessant ist, dass sich die annähernd lineare Geometrie des MNC-Clusters,d er innerhalb des Nicht-IPR-CYCF MNC@C 2v (19138)-C 76 (M = Tb,Y )e ingeschlossen ist, vçllig von den dreieckfçrmigen Konfigurationen des MNC-Clusters innerhalb der IPR-CYCFs MNC@C 82 (M = Tb,Y )u nterscheidet.…”

[33,43] Dieser Befund ist ein Meilenstein, da zum ersten Mal solch eine hohe,d urch die fünf DFP-Paare verursachte Spannung aus dem Nicht-IPR-Käfig #271 C 50 durch zehn angelagerte Chloratome wirksam freigesetzt werden konnte.2 016 wurde die chemische Oxidation von C 50 Cl 10 untersucht, die das Monoxidprodukt #271 C 50 Cl 10 Om it hoher Regioselektivitätl ieferte.…”
