Abstract
Bridging hydrido ligands possibly cause the magnetic behavior of the Cp*Co dimer formulated by Schneider et al. as Cp*CoCoCp* (Angew. Chem. Int. Ed. 1992, 30, 1124). This would agree with the calculated electron structures of the model compound CpCoCoCp and the hydrido complexes derived from them. Also the lack of reactivity of the dimer's “naked” CoCo double bond toward CO and ethylene can be explained without difficulty by a stabilizing influence of bridging hydrido ligands. The results of this theoretical study will certainly spark further investigations.Keywords
