Novel multi-proton carrier complex as an efficient proton conductor at high temperatures

"three imidazole (HIm) and three imidazolate (Im-) groups attached to central ruthenium (III) ion (Ru3+)... each of six imidazole groups attached to Ru3+ ion acts as proton transmitter... 6 times more potent than individual HIm molecules... at temperature more than –70°C proton conductivity resulted from individual localized rotations of HIm and Im- groups and proton jump to other Ru(III)complexes in crystal via hydrogen bonds... superior proton conductivity at high temperatures"
