9.2.2.3 Solution NMR
To complement our solid state XRD results on 16 with solution studies, we performed 1 H, 13 C
and
89 Y NMR at room temperature on 16a redissolved in H 2 O/D 2 O.
1 H NMR (Figure 9.30) spectrum exhibits the one signal at 1.76ppm, and 13 C NMR (Figure 9.31)
spectrum exhibit two signals 22.1 and 181 ppm and 89 Y NMR (Figure 9.32) spectrum exhibit
two signals at 49.0 and 71.0 ppm which are fully consistent with the solid state structure.
