We　have　designed　and　synthesized　a　family　of　dinuclear　cyanido-bridged　complexes　[PY5Me(2)Ru(mu-CN)Ru(dppe)CpMen][PF6](2)　(PY5Me(2)　=　2,6-bis　(1,1-bis(2-pyridyl)ethyl)　pyridine,　Cp　=　cyclopentadienyl,　n　=　0,　2[PF6](2);　n　=　1,　3[PF6](2);　n　=　5,　4[PF6](2))　by　using　a　mononuclear　complex　[PY5Me(2)Ru(mu-CN)][PF6]　(1)　as　the　pre-cursor.　All　the　three　complexes　have　been　fully　characterized　by　including　single-crystal　X-ray　diffraction　analysis.　The　one-electron　oxidation　complexes　2(3+),　3(3+)　and　4(3+)　obtained　in　situ　all　show　a　MMCT　absorption　band　in　the　visible　range.　The　MMCT　energy　increases　as　the　redox　potential　of　the　N-terminal　fragments　decreases,　and　the　redox　potential　decreases　as　the　number　of　methyl　groups　on　the　cyclopentadiene　of　the　cyanido-nitrogen　coordi-nated　Ru　metal　increases,　supported　by　the　TDF/TDDFT　calculations.
