A reaction between N2 and trans-RuIICl2L (L=2,5,9,12-tetramethyl-2,5,9,12-tetraazatridecane) in aqueous solutions has been investigated by XAFS spectroscopy. Ru K-edge EXAFS clearly revealed that there exists an N2-bridged binuclear complex and that the Ru-Ru distance is 4.96 Å with the coordination number of 0.5. The Ru K-edge energies of the N2 complexes are closer to that of RuIIICl2L+ rather than that of RuIICl2L, indicating back donation from the Ru dπ to the N2 π* orbitals.
