Self-assembly of supramolecular networks based on biphosphopentamolybdate and copper–organic units
Two polyoxometalates (POMs)-based hybrid supramolecular materials have been synthesized based on biphosphopentamolybdate and copper–organic units under hydrothermal conditions, namely, [(HPO4) 2Mo 5O 15][Cu I(4,4′-bipy)] 2[Cu II(en) 2]·6H 2O ( 1) and [(HPO 4) 2Mo 5O 15][Cu I(4,4′-bipy)] 4·6H 2O ( 2)...

2) (en = ethylenediamine and 4,4′-bipy = 4,4′-bipyridine). Their crystal structures have been characterized by elemental analysis, IR, thermal gravimetric analysis (TGA), and single-crystal X-ray diffraction analysis. The novel 2D supramolecular sheet is formed via weak copper–oxygen interaction and hydrogen bonding in
1. The fascinating structural feature of
2 is that the biphosphopentamolybdate polyanion acts as a pillar to link Cu
I centers and shows six-connected nodes. The electrochemical behaviors of hybrid materials have been studied in detail.
