dc.description.abstractThe ditopic germanium complex FGe(NIPr)2Ge[BF4] (3[BF4]; IPr=1,3‐bis(2,6‐diisopropylphenyl)imidazolin‐2‐ylidene) is prepared by the reaction of the amino(imino)germylene (Me3Si)2NGeNIPr (1) with BF3⋅OEt2. This monocation is converted into the germylene‐germyliumylidene 3[BArF4] [ArF=3,5‐(CF3)2‐C6H3] by treatment with Na[BArF4]. The tetrafluoroborate salt 3[BF4] reacts with 2 equivalents of Me3SiOTf to give the novel complex (OTf)(GeNIPr)2[OTf] (4[OTf]), which affords 4[BArF4] and 4[Al(ORF)4] [RF=C(CF3)3] after anion exchange with Na[BArF4] or Ag[Al(ORF)4], respectively. The computational, as well as crystallographic study, reveals that 4+ has significant bis(germyliumylidene) dication character.Double charge: A monocationic four‐membered germacycle is prepared by fluorination of an amino(imino)germylene followed by fluoride abstraction. Computational analysis of the bonding situation indicates a dominant germylene‐stabilized germyliumylidene character. Its reaction with Me3SiOTf affords a unique triflate‐substituted germylene‐germyliumylidene with pronounced dicationic bis(germyliumylidene) character.
