Three new POM-based coordination polymers with 1,3,5-tris(1-imidazolyl)benzene ligand: syntheses, structures and proton conductivity

Three POM-based coordination polymers with 1,3,5-tris(1-imidazolyl)benzene have been synthesized. 1 exhibits a rare 3,6-connected pyr topology; 2 and 3 reveal 3D hydrogen-bonded structures with good proton conductivity.
