A coordination network containing non-coordinating polyoxometalate clusters as counterions

This report describes the synthesis and characterization of a 2D coordination network that directly incorporates an aniline-functionalized polyoxometalate (POM) cluster. By reacting a cobalt(II) salt of the POM cluster [Mo12O46(AsC6H4NH2)4]4– with a bifunctional ligand, 4,4ʹbipyridylethylene, a 2D coordination network was synthesized through a self-assembly process. The POM behaves as a non-coordinating anion and does not interfere with the coordination network other than occupying space. Thermal analysis reveals that the structure is stable to 350 °C.
