Fig. 3. Arrhenius plots for the proton conductivity of pristine samples of (a) [Gd(H4nmp)(H2O)2]Cl·2H2O (1) and (b) [Gd2(H3nmp)2]·xH2O (2) (x = 1 to 4) measured at variable RH values ( – 98%, ◆ – 80%, ▲ – 60%, [black circle] – 40%, and ■ – 20%), with the 1st run data in green, 2nd run data in orange and 3rd run in black.
