- This value was based on the geometric resolution. See ref 2.

Organometallics , 6 : 2319 was questioned (Y. Wang, K. Angermund, R. Goddard, C. Krüger, J. Am. Chem. Soc., 109, 587(1987), because the computed structure was an idealized C 3v whereas the site symmetry of the complex in the crystal is only Cs. To our knowledge 2t represents the first trigonal arenetricarbonylmetal complex that retains its idealized point group symmetry in the crystal and may therefore be suitable for comparison with computational charge densities.
- A least-squares fit of the geometries of I and II was performed using a routine in the Uranus86 package of programs. We thank Simon K. Kearsley for the use of these routines. Cartesian coordinates of molecule II were first inverted. The centroids of each molecule were places at the origin and a rotation matrix was computed to bring paired atoms into register. The largest deviation was between C3 and C12 (0.243 Å).
