Figure 1
A perspective view of a single molecule of (I), 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 Os2—H—B6 bridging H atom, shown to be present by NMR spectroscopy, was not located from the X-ray data. |
