Abstract

Two unique 22-core sandwich {[Mn₆Mo₆O₃₇]Ln₃[MnMo₆O₂₄]} (Ln = La or Pr) units have been assembled, featuring an undisclosed {Mn₆Mo₆} cluster. This assembly is subsequently integrated into two three-dimensional polyoxometalate organic frameworks, which exhibit one-dimensional hydrophilic hexagonal channels formed by six intertwined 6₃ helical chains, leading to effective proton conduction primarily facilitated by an abundance of water molecules within the channels.
