The reaction of a digermyne Ar';GeGeAr'; (Ar'; = C(6)H(3)-2,6-(C(6)H(3)-2,6-Pr(2)(i))(2)) with AgSbF(6) at -40 degrees C forms the complex (AgAr';GeGeAr';)(+)SbF(6)(-), which provides the first example of a heavier group 14 element alkyne analogue behaving as a pi donor to a transition metal. The cation (AgAr';GeGeAr';)(+) is best described as a hybrid of a pi-complex and a sigma-metallacyclopropene structure.
