and 23+ were synthesized and well characterized. For the two-electron oxidized 14+ and 24+, their Fourier transform infrared (FTIR) and UV–vis–NIR spectra were investigated by employing spectroelectrochemical methods. The time-dependent density-functional theory (TDDFT) calculations and the experimental results indicate that the one-/two-electron oxidized mixed-valent compounds belong to Class II–III
