The syntheses of three strained silicon or germanium heterocyclotriynes, from the dilithium dianion of 2,2′-diethynyltolane (Li2(OBET)) and the dialkyldichlorosilanes or dialkyldichloro-germane, are described. Reactions of the heterocyclynes with Ni(COD)2 give the nickel(0) complexes in very high yield. The heterocyclynes and their nickel complexes have been characterized by a variety of spectral techniques, and the X-ray crystal structures of compounds Si(i-Pr)2(OBET), Ni[Si(i-Pr)2(OBET)], SiPh2(OBET), Ni[SiPh2(OBET)], GePh2-(OBET), and Ni[GePh2(OBET)] are reported. The heterocyclynes and their nickel complexes possess isomorphous structures.
