Admixture of the lithium salt of the bulky ligand 2,6-dimesitylbenzoate [ArCO2]- with [Cu(CH3CN)4]O 3SCF3 yielded the dicopper(I,I) complex [(ArCO 2)2Cu2(THF)2)] (1), which upon oxidation with AgX (X = SbF6- or ClO4 -) in THF afforded the mixed-valent complexes [(ArCO 2)2Cu2(THF)2]SbF6 (2) and [(ArCO2)2Cu2(THF)3]ClO4 (3), respectively. Fully delocalized mixed-valent (Cu1.5Cu 1.5) formulations for 2 and 3 were determined on the basis of X-ray crystallography and UV-vis, resonance Raman, 1H NMR, and EPR spectroscopy. Notably, solvent dependent UV-vis spectra suggest that THF and/or counter ion coordination influence the intermetal bonding interactions in the mixed-valent cores.
