  Co-2(CO)(6)} groups were attached to p-diethynylbenzene-based acetylenes giving complexes of general formula [Co-2(CO)(6)(mu(2)-eta(2:2)-RC2C6H4C2R')] ((4): R = R' = H; (4a): R = SiMe3, R' = H; (4b): R = R' = SiMe3); [Co-2(CO)(6)}(2)(mu(4)-eta(2:2:2:2)-RC2C6H4C2R')] ((3): R = R' = H; (3a): R = SiMe3, R' = H; (3b): R = R' = SiMe3); [Co-2(CO)(6)}(4)(mu(8)-eta(2:2:2:2:2:2:2:2)-R2C6H4C2C2C6H4C2R)]((5): R = H; (5b):R = SiMe3). The addition of Co-4(CO)(12) to p-diethynylbenzene and to 4 was also investigated, producing [Co-4(CO)(8)(mu-CO)(2)}(mu(4)-HC2C6H4C2H)] (6) and [Co-2(CO)(6)} (Co-4(CO)(8)(mu-CO)(2)}(mu(8)-HC2C6H4C2H)] (7). The syntheses of the acetylenic derivatives of C-60 [(trimethylsilyl)ethynyl] hydrofullerene [60] (8a) and (phenylethynyl) hydrofullerene[60] (9) and the new ligand [(trimethylsilyl)diethynylbenzene]hydrofullerene[60] (10a) were performed and the resulting acetylenes were reacted with dicobaltoctacarbonyl giving the corresponding complexes [(trimethylsilyl)(dicobalthexacarbonyl)ethynyl]hydrofullerene[60] (11a), (phenylethynyl)(dicobalthexacarbonyl)hydrofullerene[60] (12) and [(trimethylsilyl)bis(dicobalthexacarbonyl)diethynylbenzene] (13a). The reaction of 1-bromo-3,5-diethynylbenzene and 1,3,5-triethynylbenzene with dicobaltoctacarbonyl resulted in the formation of [HC2Co-2(CO)(6)}](2)C6H2Br (16) and [HC2Co-2(CO)(6)}](2)C6H3 (15) as expected. Crystals of 3a, 3b, 4, 4b, 15 and 16 suitable for single-crystal X-ray diffraction were grown and the molecular structures of these compounds an discussed. (C) 1999 Elsevier Science S.A.
