Structural-dynamic approach and path analysis of the intramolecular electron transfer in the bridged complexes [(NH3)5Ru-py-(C2H2) n -py-Ru(NH3)5]5+ withn = 0,1,2,3

The electron interaction transfer paths in the mixed-valence complexes(NH₃)₅Ru-py-(C₂H₂)_n-py-Ru(NH₃)₅]⁵⁺ are analyzed in the framework of perturbation theory. A structural-dynamic approach to treatment of the intramolecular electron transfer is proposed. This approach is based on the solution of the nonstationary Schrödinger equation in a basis of many-electron functions describing separate structural sites of the electron-transport chain Ry^II→pyridyl→ C₂H₂)_n→pyridyl→Ru^III.
