For a long time, since the pioneering work of Robson and coworkers in 1990 [1], aromatic nitrogen-containing heterocycles such as the exo bidentate ligand 4,4¡¯-bipyridine have commonly been employed as building blocks in designing coordination polymers, constructing supramolecular architectures [2], storing energy and catalyzing oxidation [3]. It is noteworthy that a variety of metal organic-inorganic hybrid materials can be prepared from 1D metal-rigid organodiamines, such as pyrazine, 4,4¡¯-bipyridine and their analogues, and sulfate building blocks. Recently, several coordination polymers containing 4,4¡¯-bipyridine and sulfate have been reported, including different metal ions for example Fe2+, Co2+, Cd2+, Zn2+, Mn2+ and Cu2+ [4,5].
