摘要：

Six FeIII centers are incorporated into the tungstophosphate anion [H2P2W12O48]12- upon reaction with FeCl3. The {P2W12Fe 6} unit thus formed has been characterized in [H4P 2W12Fe9O56(OAc)7] 6- and [H56P8W48Fe 28O248]28-. The latter is a supramolecular polyoxotungstate in which each of the four {P2W12Fe 6} units is connected by three Fe-O-Fe bridges (see structure). Magnetic studies indicate strong antiferromagnetic coupling between the Fe III centers. (Figure Presented) © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
