Evidence for two weakly coupled diruthenium(II,III) subsystems in symmetrical tetranuclear complexes {(μ4-TCNX)[Ru(NH3)5]4}8+ (TCNX = TCNE, TCNQ)2061993MO TCNQ complex complex;TCNE complex;frontier complex;magnetic complex;redox complex;spectra electronic moment potential ruthenium structure The air-stable complexes {(μ4-TCNX)[Ru(NH3)5]4}(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 \textgreek{m}eff = 2.7 suggest a weak interaction between two mixed-valent malonodinitrilato/(Ru2.5)2 subsystems.
