| Abstract: | The ditopic germanium complex FGe(NIPr)2GeBF4] ( 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 NaBArF4]. The tetrafluoroborate salt 3 BF4] reacts with 2 equivalents of Me3SiOTf to give the novel complex (OTf)(GeNIPr)2OTf] ( 4 OTf]), which affords 4 BArF4] and 4 Al(ORF)4] RF=C(CF3)3] after anion exchange with NaBArF4] or AgAl(ORF)4], respectively. The computational, as well as crystallographic study, reveals that 4 + has significant bis(germyliumylidene) dication character. |
