Electron transfer in the [Pt(NH3)(sub 4)](super 2+) [W(CN)(sub 8)](super 3-) donor-acceptor system. The environment effect: a time-dependent density functional study

The electron transfer mechanism in the [Pt(NH3)(sub 4)](super 2+) [W(CN)(sub 8)](super 3-) donor-acceptor system was investigated by a series of quantum mechanical calculations, based on the B3LYP hybrid functional and the time-dependent density functional theory algorithm implemented in the Gaussian98 package. It was seen that both solvent and interaction with [W(super V)(CN)(sub 8)](super 3-) destabilize Pt d orbitals, but its presence protects Pt from the solvent interactions.
