Streszczenie

A number of new POM-based coordination polymers, including two-dimensional (NH4)4{[Ca(H2O)5][P2Mo5O23]}·3H2O (4) (bpy = 2,2′-bipyridine), and a rare anion-based (NH4)5[CoIII(bpy)3]{[Ca(H2O)4]2[Ca(H2O)]6[PMo6O22(PO4)3]2}·17H2O (3), as well as three-dimensional (NH4)8[CoIII(bpy)3]2{[Ca(H2O)3]2[P2Mo5O23]3}·21H2O (2) have been prepared using a facile wet-chemistry approach and have been characterized by X-ray diffraction analysis and a variety of physicochemical methods. The self-assembly in the above compounds has been rendered by the use of Ca2+ ions as a suitable linker in the network formation. Moreover, Ca2+ions were also involved in the formation of an extremely rare type of POM anion {[Ca(H2O)]6[PMo6O22(PO4)3]2}12–. The synthesis attempt without the alkaline-earth metal led, predictably, to the formation of the discrete Strandberg-based compound (NH4)3[CoIII(bpy)3][P2Mo5O23]·14H2O (1). Thus, the present work reports on a suitable strategy to influence complex POM-based systems towards self-organization into multidimensional structures of higher hierarchy. The obtained compounds have been shown to possess electrocatalytic activity towards the reduction of iodates(V).
