The electrochemical Seebeck coefficient ( = d/d; and are the redox potential and temperature, respectively) is important parameter for thermoelectric conversion. Here, we found that of Fe/Fe in dimethyl sulfoxide (DMSO) with small amount of 19 M LiCl aqueous solution exhibits a crossover behavior from 1.4 mV K (20 °C ≤ ≤ 40 °C) to ≈0 mV K (50 °C ≤ ≤ 80 °C). The molar absorption () spectra revealed that the crossover is ascribed to the transformation of the dominant Fe complex from [FeL] (L is solvent molecule) to [FeCl].
