Abstract

A digermanium(III) 1,2-dication comprises two cationic centers located at two interconnected Ge atoms. The strong Coulombic repulsion between two positively charged germanium cations hinders their bond formation. Balancing these two oppositions was achieved by using amidinate and cyclic (alkyl)amino carbene (cAAC)-phosphinidenide ligands, where an amidinato cAAC-phosphinidenidogermylene complex, [LGeP(cAAC_Me)] (2, where L = PhC(NtBu)₂, cAAC_Me = :C{C(Me)₂CH₂C(Me)₂NAr}, and Ar = 2,6-iPr₂C₆H₃), underwent one-electron oxidation with a bis(phosphinidene) radical cation, [(cAAC_Me)P]₂^•+, to form a digermanium(III) 1,2-dication, [LGeP(cAAC_Me)]₂²⁺, in compound 4.
