Concomitant spin-canted antiferromagnetic ordering and proton conduction in homometallic and homoleptic coordination polymers

Two unprecedented oxonate based 1D coordination polymers with Fe(II) and Co(II) have been synthesized. A detailed magnetic investigation revealed that these complexes are the first oxonate based systems to exhibit spin canted antiferromagnetic ordering at low temperatures. Proton conductivity studies of the complexes showed good proton conduction ability at elevated temperatures and under high humidity conditions.
