Pentamethylcyclopentadienyl transition metal complexes. 9. Reactions and solid-state and solution behavior of dinuclear cobalt(II) complexes [C5Me5Co(μ-X)]2

Reaction of C5Me5Li (Cp*Li) with Co(II) halides, CoX2 (X = Cl, Br, I), or the hexaammine [Co-(NH3)6] (BF4)2 in 1:1 molar ratio leads to binuclear Co(II) half-sandwich complexes (Cp*Co)2(μ-X)2 (1, X = Cl, Br, I, NH2). Starting from 1a and 1b (X = Cl, Br), derivatives with the bridging ligands NMe2, OEt, SMe, and PPh2 are obtained. The stability of the compounds range from nearly air stable (X = SMe) to extremely air sensitive and thermally labile (X = I). Magnetic measurements show a strong antiferromagnetic interaction of the two d7 Co centers. EPR, 1H NMR, and electrochemical investigations were used to demonstrate a monomer/dimer equilibrium in solution. The binuclear halo compounds are cleaved by donor bases (pyridine and phosphines) to yield mononuclear complexes Cp*CoXL.
