DOI: 10.1039/c9sc05904k
Abstract: Weakly Coordinating Anions (WCAs) containing electron deficient delocalized anionic fragments that are reasonably inert allow for the isolation of strong electrophiles. Perfluorinated borates, perfluorinated aluminum alkoxides, and halogenated carborane anions are a few families of… read more here.

DOI: 10.1039/d2sc04846a
Abstract: Synthesis of the first thorium-containing clusterfullerenes, ThC2@Cs(6)–C82 and ThC2@C2(5)–C82, is reported. These two novel actinide fullerene compounds were characterized by mass spectrometry, single-crystal X-ray diffraction crystallography, UV–vis–NIR spectroscopy, and theoretical calculations. Crystallographic studies reveal that… read more here.
