Abstract

Abstract: The ditopic germanium complex FGe(NIPr)2 Ge[BF4 ] (3 [BF4 ]; IPr=1, 3‐bis(2, 6‐diisopropylphenyl)imidazolin‐2‐ylidene) is prepared by the reaction of the amino(imino)germylene (Me3 Si)2 NGeNIPr (1 ) with BF3 ⋅OEt2 . This monocation is converted into the germylene‐germyliumylidene3 [BAr F 4 ] [Ar F =3, 5‐(CF3 )2 ‐C6 H3 ] by treatment with Na[BAr F 4 ]. The tetrafluoroborate salt3 [BF4 ] reacts with 2 equivalents of Me3 SiOTf to give the novel complex (OTf)(GeNIPr)2 [OTf] (4 [OTf]), which affords4 [BAr F 4 ] and4 [Al(OR F )4 ] [R F =C(CF3 )3 ] after anion exchange with Na[BAr F 4 ] or Ag[Al(OR F )4 ], respectively. The computational, as well as crystallographic study, reveals that4 + has significant bis(germyliumylidene) dication character.
