Kurzfassung:
A number of new POM‐based coordination polymers, including two‐dimensional (NH 4 ) 4 {[Ca(H 2 O) 5 ][P 2 Mo 5 O 23 ]} · 3H 2 O ( 4 ) (bpy = 2,2′‐bipyridine), and a rare anion‐based (NH 4 ) 5 [Co III (bpy) 3 ]{[Ca(H 2 O) 4 ] 2 [Ca(H 2 O)] 6 [PMo 6 O 22 (PO 4 ) 3 ] 2 } · 17H 2 O ( 3 ), as well as three‐dimensional (NH 4 ) 8 [Co III (bpy) 3 ] 2 {[Ca(H 2 O) 3 ] 2 [P 2 Mo 5 O 23 ] 3 } · 21H 2 O ( 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 Ca 2+ ions as a suitable linker in the network formation. Moreover, Ca 2+ ions were also involved in the formation of an extremely rare type of POM anion {[Ca(H 2 O)] 6 [PMo 6 O 22 (PO 4 ) 3 ] 2 } 12– . The synthesis attempt without the alkaline‐earth metal led, predictably, to the formation of the discrete Strandberg‐based compound (NH 4 ) 3 [Co III (bpy) 3 ][P 2 Mo 5 O 23 ] · 14H 2 O ( 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).
