Two new hybrid materials [Fe(bipy)3]3[ZnW 12O39(OH)Fe(bipy)2(H2O)] 2 and [Fe(bipy)3]2[CoW12O 40] were obtained by hydrothermal synthesis. They contain [Fe(bipy)3] n+ (bipy = 2,2'-bipyridyl; n = 2 or 3) cations and Keggin-type polyoxotungstate anions. Both have been characterized by elemental analysis, FT-IR spectroscopy, 1H-NMR spectrometry, and single crystal X-ray crystallography. The anion in the former salt features [FeII(bipy)2(OH2)]2+ units covalently bound via a W=O-Fe bridge to the protonated anion [ZnW 12O39(OH)]5. The latter salt contains discrete [CoW12O40]6 anions. © CSIRO 2010.
