The use of methane as a reactive gas dramatically increases the selectivity arc-discharge synthesis M-Ti-carbide clusterfullerenes (M=Y, Nd, Gd, Dy, Er, Lu). Optimization process parameters allows Dy2TiC@C80-I and its facile isolation in single chromatographic step. A new type cluster with an endohedral acetylide unit, M2TiC2@C80, is discovered along second isomer M2TiC@C80. Dy2TiC@C80-(I,II) Dy2TiC2@C80-I are shown to be single-molecule magnets (SMM), but presence carbon atom Dy2TiC2@C80...
Abstract The formation of endohedral metallofullerenes (EMFs) in an electric arc is reported for the mixed‐metal Sc–Ti system utilizing methane as a reactive gas. Comparison these results with those from Sc/CH 4 and Ti/CH systems well syntheses without revealed strong mutual influence all key components on product distribution. Whereas atmosphere alone suppresses empty cage fullerenes, forms mainly fullerenes. In contrast, main fullerene products are Sc C 2 @C 80 (the most abundant EMF this...

Abstract Methan erhöht als reaktives Gas drastisch die Selektivität der Lichtbogensynthese von M‐Ti‐Carbidclusterfullerenen (M=Y, Nd, Gd, Dy, Er, Lu). Ferner ermöglicht Optimierung Prozessparameter Synthese Dy 2 TiC@C 80 ‐I und dessen einfache Isolierung in einem einzigen chromatographischen Schritt. Neben zweiten Isomer des M wurde außerdem eine neue Clusterart mit endohedraler Acetylidgruppe, TiC @C , entdeckt. Weiterhin wirken ‐(I,II) Einzelmolekülmagenten (SMMs), jedoch verschlechtert...
A key parameter for the low-temperature magnetic coupling of in dinuclear lanthanide single-molecule magnets (SMMs) is barrier ${U}_{FA}$ resulting from exchange and dipole interactions between two $4f$ moments. Here we extend pseudospin model previously used to describe ground state endofullerenes account variations orientation single-ion anisotropy axes apply it SMMs ${\mathrm{Dy}}_{2}\mathrm{ScN}$@${\mathrm{C}}_{80}$ ${\mathrm{Dy}}_{2}\mathrm{TiC}$@${\mathrm{C}}_{80}$. While x-ray...
The clusterfullerenes with carbon in the endohedral clusters is most versatile family terms of possible cluster compositions 1,2 . In addition to its obvious role forming fullerene cage, also found core several types clusters, including carbide clusterfullerenes, cyano and more complex cluster. Two EMFs single were reported so far, Sc3CH@C80, which central atom bonded by a hydrogen 3 , TiLu 2 C@C 80 μ -carbido ligand forms double bond Ti 4 Both structures as minor components synthesis other...
