The syntheses of (η5-cyclopentadienyl)(η4 -tetraphenylcyclobutadiene)cobalt units bridged by buta-1,3-diyne, octa-1,3,5,7-tetrayne, and dodeca-1,3,5,7,9,11-hexayne units (15, 18, 21) are reported. All three species could be obtained by Hay coupling of the corresponding mono-, di-, and triyne units 14, 17, and 20. In the case of 14-17 and 21, the molecular structures were confirmed on the basis of X-ray studies on single crystals. Cyclic voltammetry revealed a weak interaction between the metal centers of 15 and no interaction between the metal centers of 18 and of 21. Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002.
