Abstract

The linear oligogermyl amide 2, Ph₃GeGeMe₂NMe₂, was obtained by reacting Ph₃GeLi with 1, Me₂Ge(Cl)NMe₂. The amide 2 was used for the synthesis of molecular oligogermanes 3, Ph₃GeGeMe₂Ge(C₆F₅)₃, and 4, [Ph₃GeGeMe₂]₂Ge(C₆F₅)₂, containing electron donor (Me, Ph) and acceptor (C₆F₅) groups, by using a hydrogermolysis reaction in n-hexane. The molecular structures of 3 and 4 were studied by XRD. It was shown that in a crystal 3 forms wide channels, in which the solvated nonpolar n-hexane molecule is present. The NMR (¹H, ¹³C and ¹⁹F), optical (UV/vis absorption, luminescence) and electrochemical (cyclic voltammetry) properties of both compounds were also studied. The impact of the substitution type by the electron withdrawing groups (at the terminal position, such as in 3, or within the compound, such as in 5), on the physical properties was also studied.
