The chemistry of f-block metal-carbon multiple bonds is underdeveloped compared to well-established carbene complexes the d-block transition metals. Herein, we report two new actinide-rare earth mixed metal carbides and nitrogen carbide cluster fullerenes, USc2C2@D5h(6)-C80 USc2NC@D5h(6)-C80, which contain U-C with triple bond character were successfully synthesized characterized by mass spectrometry, UV-vis-NIR spectroscopy, Fourier transform infrared single crystal X-ray diffraction, DFT...
Metal–metal bonding is crucial in chemistry for advancing our understanding of the fundamental aspects chemical bonds. bonds based on alkaline-earth (Ae) elements, especially heavier Ae elements (Ca, Sr, and Ba), are rarely reported due to their high electropositivity. Herein, we report two heteronuclear di-EMFs CaY@Cs(6)-C82 CaY@C2v(5)-C80, which contain unprecedented single-electron Ca–Y metal–metal These compounds were characterized by single-crystal X-ray crystallography, electron...
Despite decades of efforts, the actinide-carbon triple bond has remained an elusive target, defying synthesis in any isolable compound. Herein, we report successful uranium-carbon bonds carbide-bridged bimetallic [U≡C-Ce] units encapsulated inside fullerene cages C72 and C78. The molecular structures UCCe@C2n nature U≡C were characterized through X-ray crystallography various spectroscopic analyses, revealing very short 1.921(6) 1.930(6) Å, with metals existing their highest oxidation states...
Understanding metal-metal bonding involving f-block elements has been a challenging goal in chemistry. Here we report series of mixed-valence di-metallofullerenes, ThDy@C2n (2n = 72, 76, 78, and 80) ThY@C2n 72 78), which feature single electron actinide-lanthanide bonds, characterized by structural, spectroscopic computational methods. Crystallographic characterization unambiguously confirmed that Th Y or Dy are encapsulated inside variably sized fullerene carbon cages. The ESR study...
Understanding the chemical behavior of actinide elements is essential for effective management and use materials. In this study, we report an unprecedented η2 (side-on) coordination U by a cyanide in UCN cluster, which was stabilized inside C82 fullerene cage. UCN@Cs(6)-C82 successfully synthesized fully characterized mass spectrometry, single crystal X-ray crystallography, cyclic voltammetry, spectroscopy, theoretical calculations. The bonding analysis demonstrates significant donation...
Abstract Actinide diatomic molecules are ideal models to study elusive actinide multiple bonds, but most of these have so far only been studied in solid inert gas matrices. Herein, we report a charged U≡N species captured fullerene cages and stabilized by the U-fullerene coordination interaction. Two clusterfullerenes, viz. UN@ C s (6)-C 82 2 (5)-C , were successfully synthesized characterized. Crystallographic analysis reveals U-N bond lengths 1.760(7) 1.760(20) Å . Moreover, was found be...
The first thorium-containing cluster fullerenes, ThC 2 @C s (6)–C 82 and (5)–C , were synthesized characterized. clusters in both C cages feature a novel bonding structure with thorium metal CC forming an isosceles triangular configuration.
Endohedral fullerenes are known for their exceptional ability to host metal clusters that contain unique bonding motifs. In this study, we report a facile strategy synthesize new family of clusterfullerenes, fluoride clusterfullerenes (FCFs).
