Figure 9.49 Polyhedral/ball and stick type structural representation of 19. Color scheme: Y, Si and WO 6
units are shown by yellow, green and red respectively.
9.2.5.3 Solution NMR
To complement our solid state XRD results on 18 with solution studies, we performed 89 Y NMR
at room temperature on 18a redissolved in H 2 O/D 2 O.
89 Y NMR (Figure 9.50) spectrum exhibits one signal at 43.11 ppm which is fully consistent with
the solid state structure.
