Figure 2
A perspective view of a single molecule of (IV), with displacement ellipsoids drawn at the 40% probability level and H atoms shown as small spheres of arbitrary radii. The phenyl groups, with the exception of the ipso-C atoms, have been omitted for clarity. The two H atoms bridging B9—H—B8 and B9—H—B10, shown to be present by NMR spectroscopy, were not located from the X-ray data. |
