Figure 9.42 Combination of polyhedral/ball-stick representation of 18. Color scheme: Ge, Y, C, H are
represented by turquoise, yellow, blue and black respectively. Red polyhedra represent WO 6 units.
9.2.4.3 Solution NMR
To complement our solid state XRD results on 18 with solution studies, we performed 1 H, 13 C,
89 Y and
183 W NMR at room temperature on 18a redissolved in H 2 O/D 2 O.
1 H NMR (Figure 9.43) spectrum exhibits the one signal at 1.82 ppm, and 13 C NMR (Figure
9.44) spectrum exhibit two signals 23.29 and 181.5 ppm and 89 Y NMR (Figure 9.46) spectrum
