Proton conductivity studies for Keplerate cluster containing compound, [Mo 72 Fe 30 O 252 (CH 3 COO) 12 {Mo 2 O 7 (H 2 O)} 2 {H 2 Mo 2 O 8 (H 2 O)}(H 2 O) 91 ] ⋅ 150H 2 O ( 1 ) have been performed. Compound 1 exhibits a conductivity value of 1.85×10 −3 S cm −1 under humidified (RH=50 %) and low temperature (<330 K) conditions. The water molecules, present in this system along with deprotonated (iron coordinated) water molecules of compound 1 , are responsible for the movement of the protons within its discrete clusters in the relevant crystals, following Grotthuss mechanism.
