Abstract

The trinuclear clusters [Pd-3(mu-dppm)(3)(CO)](2+) and [PtPdCo(mu-dppm)(2)(CO)(3)(CN(t)Bu)](+) exhibit a large and a small cavity, respectively, formed by the phenyl rings of the bridging diphosphine ligands. Their binding constants (K-11) with halide ions (X(-)) were obtained by UV-Vis spectroscopy. The binding ability varies as I->Br->Cl-, and [Pd-3(mu-dppm)(3)(CO)](2+) much greater than [PtPdCo(mu-dppm)(2)(CO)(3)(CN(t)Bu)](+). The MO diagram for the related cluster [Pd2Co(mu-dppm)(2)(CO)(4)](+) has been addressed theoretically in order to predict thenature of the lowest energy electronic bands. For this class of compounds, the lowest energy bands are assigned to charge transfers from the Co center to the Pd-2 centers.
