  • Although neutral and anionic low-valent aluminium complexes are widespread, their cationic counterparts have remained rare. Now, a salt of [Al(AlCp*)3]+ featuring a formal low-valent Al+ cation has been isolated that dimerizes in concentrated solutions and the solid state, and also forms Al4 clusters on coordinating with Lewis bases.

  • The in situ generation of reactive (di)gallenes from a gallium–fluorobenzene complex and commercial chiral and achiral bisphosphine ligands is presented. The Ga(I) complex cations can undergo reversible cycloadditions to 1-alkenes and bond insertions into H–Si and H–B bonds.

  • While the development of weakly coordinating anions received much attention, the progress on weakly coordinating and inert solvents almost stagnated. Here the authors report that strategic F-substitution of fluorobenzene solvents strongly increases the redox potentials of Ag+ and NO+ salts and tolerates high potentials of perfluorinated radical cations.

  • Carbonyl complexes have been studied extensively thanks to their rich substitution and redox chemistry, but most homoleptic transition metal carbonyl complexes isolated in the condensed phase are neutral or anionic. Here, the authors isolate two homoleptic carbonyl radical cations in the condensed phase; both 17-electron [Cr(CO)6]•+ salts.

  • Group 13 metals such as gallium and indium with oxidation states of +I tend to disproportionate into more stable 0 and +III states. Here, the authors report that with a 2,2'-bipyridine ligand Ga(+I) forms a paramagnetic mononuclear Ga(+III) complex, whereas the indium analogue aggregates forming cationic clusters retaining the +I state.
