Abstract

{Cu4Br5[(η5-C5H4PPh2)(η5-C5H5)Co]4}[PF6]3, [(η5-C5H4PPh2)(η5-C5H5)Co]+ = ((η5-cyclopentadienyl)[η5-1-(diphenylphosphino) cyclopentadienyl] cobaltocenium) and {Ag(NO3)(CH3COCH3)[(η5-C5H4PPh2)(η5-C5H5)Co]}n[PF6]n have been synthesized and characterized by elemental analyses, infrared spectroscopy, X-ray diffraction techniques, and by cyclic voltammetry. {Cu4Br5[(η5-C5H4PPh2)(η5-C5H5)Co]4}[PF6]3 contains four coplanar copper atoms bridged by four μ-Br and one central μ4-Br occupying the apex of a square pyramid, and {Ag(NO3)(CH3COCH3)[(η5-C5H4PPh2)(η5-C5H5)Co]}n[PF6]n affording a 1-D coordination zigzag polymer.
