Die Reaktion von Bisdicyclohexylphosphinoethan (dcpe) und den subvalenten MI‐Quellen [MI(PhF)2][pf] (M=Ga+, In+; [pf] −=[Al(ORF)4]−; RF=C(CF3)3) ergab die Salze [{M(dcpe)}2][pf]2, die die ersten bisher dokumentierten dikationischen, trans‐gefalteten Digallen‐ und Diindenstrukturen enthalten. Die nicht‐klassischen MI⇆MI‐Doppelbindungen sind überraschend kurz und zeigen eine ditetrylenartige Struktur...
The reaction of bisdicyclohexylphosphinoethane (dcpe) and the subvalent MI sources [MI(PhF)2][pf] (M=Ga+, In+; [pf]−=[Al(ORF)4]−; RF=C(CF3)3) yielded the salts [{M(dcpe)}2][pf]2, containing the first dicationic, trans‐bent digallene and diindene structures reported so far. The non‐classical MI⇆MI double bonds are surprisingly short and display a ditetrylene‐like structure. The bonding situation was...
