摘要：

Cocondensation of cobalt atoms with 1,4-di-tert-butylbuta-1,3-diene affords the stable, paramagnetic butadiene sandwich compound [Co(eta-C4H4But2)2], which is a reactive source of Co0 fragments; reduction Of [Co(eta-C4H4But2)2] with potassium affords the first crystallographically characterised homoleptic butadiene sandwich complex, [Co(eta-C4H4But2)2]-, in which the bonding is that of a genuine diene rather than a metallacyclopentene.
