A first robust complex of tetradentate TCNQ. Evidence for two weakly coupled diruthenium(II,III) subsystems in symmetrical tetranuclear complexes (μ4-TCNX)Ru(NH3)548+ (TCNX = TCNE, TCNQ)
The air-stable complexes (μ4-TCNX)Ru(NH3)54(PF6)8 which contain reduced TCNX ligands show spectroscopic equivalence of the four metal coordination sites on the 1H NMR and vibrational time scales and very close lying frontier orbitals (UV-Vis-NIR, electrochem.). Both the two-electron oxidn. behavior and the magnetic moment of meff = 2.7 suggest a weak interaction between two mixed-valent malonodinitrilato/(Ru2.5)2 subsystems. on SciFinder(R)
