Triple-decker complexes with a bridging diborolyl ligand CpCo(mu-1,3-C3B2Me5)M(CO)(3) (M = Mn, 2; Re, 3), CpCo(mu-1,3-C3B2Me5)Ru(CO)(2)Cl (4) and CpCo(mu-1,3-C3B2Me5)Ru(CO)(mu-CO)(2)Ru(CO) Cp (5) were synthesized by reaction of the sandwich anion [CpCo(1,3-C3B2Me5)](-) (1) with [(naphthalene) Mn(CO)(3)](+), [Re(CO)(3)(THF)(2)Br](2), or [Ru(CO)(3)Cl-2](2). Structures of 4 and 5 were determined by X-ray diffraction. The spectroelectrochemical behaviour of compounds 2 and 3 was studied. IR-spectroscopical and computational data suggest that anion 1 is significantly stronger donor than Cp- but slightly weaker than Cp*(-).
