Proton-conductive metal-organic frameworks (MOFs) have attracted great attention for their promising application in membrane fuel cells.To explore proton-conductive MOFs with high performance,here we present four lanthanide-hypophosphite frameworks with distinct amine guests.These complexes possess a general formula[AH][Gd2(H2PO2)7](AH =protonated amines).Due to the rich hy-drogen bond networks,complex 1 with guanidinium as guest shows high proton conductivity of 1.75 × 10-2 S·cm-1 at a relative hu-midity of 97% (368 K).We also studied the magnetic properties of complex 1 and reveal that the hypophosphite ligand transfers weak antiferromagnetic interactions between Gd3+ ions.
