A ditetrylyne as a π-electron donor: synthesis and characterization of [AgAr'GeGeAr'](+)SbF6(-) and [Ag2Ar'GeGe(F)Ar'](+)SbF6(-) (Ar' = C6H3-2,6(C6H3-2,6-Pr(i)2)2).
The reaction of a digermyne Ar'GeGeAr' (Ar' = C(6)H(3)-2,6-(C(6)H(3)-2,6-Pr(i)(2))(2)) with AgSbF(6) at -40 °C forms the complex (AgAr'GeGeAr')(+)SbF(6)(-), which provides the first example of a heavier group 14 element alkyne analogue behaving as a π donor to a transition metal. The cation (AgAr'GeGeAr')(+) is best described as a hybrid of a π-complex and a σ-metallacyclopropene structure.
