Electron Transfer between Ruthenium (II)-(trisbipyridine) Ru and Cobalt(III)-(polypyridyl) Co at , , and Acetone Solvents

A theoretical calculations of electron transfer at metals interfaces are performed to study the electron transfer for Ru (phen) ^2+ 3 - Co (phen) ^3+ 3 CH3 CN ,, CH3 OH and acetone solvents. This study is based on the assumption that metals have a continuum of donor s and acceptor s states .The rate of electron transfer,the reorganization energy ,the enthalpy , the effective free energy, and coupling coefficient of matrix elements ,V, were calculated for the donor Ru(phen) ^2+ 3 and acceptor in variety of solvents. The results show that the electron transfer in Ru(phen) ^2+ 3 system at solvents is fast and efficient. Our calculations show good agreement with the experimentally observed results for metals complex.
