Two Tetracobalt Cluster Complexes: Preparation And Molecular Structures Of Co4(Mu-Dppm)(2)(Mu-Co)(3)(Co)(5) And Co-4(Mu-Co)(3)(Co)(6)(Eta-C6h6)
AUSTRALIAN JOURNAL OF CHEMISTRY（2001）
摘要
The crystal and molecular structures of the title complexes (1) and (2) are described. Each contains a Co-4 tetrahedron, one face of which is edge-bridged by three mu -CO ligands. In (1), a pair of mutually orthogonal Co-Co bonds are bridged by the two dppm (dppm = bis(diphenylphosphino)methane) ligands. The structure of the benzene complex was determined at 153 and 300 K; as with other arene-Co-4 clusters, the eta (6)-benzene ligand sits on the apical (i.e. non-CO-bridged) Co atom.
