Abstract
Two dimeric head-on complexes of yttrium containing silico- and germanotungstate were isolated from the one-pot reaction of Y(NO 3) 3·6H 2O with the lacunary Na 10[MW 9O 34]·16H 2O (M = Si and Ge) building blocks in an acetate buffer at pH 4.5. Both polyanions were structurally characterized using various solid-state analytics, such as single-crystal X-ray diffraction, single-crystal X-ray analysis shows that both polyanions crystallize in the monoclinic crystal system (S.G. P2 1/ c). FT-IR spectroscopy, or thermogravimetric analysis. The stability of the polyanion in aqueous solution was studied by multinuclear NMR spectroscopy ( 183W, 89Y, 29Si, 13C, and 1H). As expected, the 183W NMR spectra display six peaks in the intensity ratio of 4:4:2:4:4:4 which indicates that both polyanions exist as dimeric entities in aqueous solution.
