“…However, we managed to deduce the correct arrangement of the boron atoms, but not the detailed arrangements of the hydrogens. This GED work was never published, but the structure may be seen in the article by Lavine and Lipscomb describing the crystallographic results [20].…”

The author has spent nearly five decades working on the molecular structure of gaseous molecules using principally the method of electron diffraction. During this time he has seen and participated in the development of the method from its crude beginning in which the diffraction patterns were measured by hand and interpreted by eye, to the powerful, nearly automatic instrument-based methods of today. Accompanying this evolution in the method is a similar evolution in the complexity of the scientific problems. Whereas in the early days the molecules studied were necessarily simple and the parameter determinations accurate to a few hundredths of anÅngström, electron diffraction today is routinely applied to molecules with a 10-fold greater numbers of parameters and yields results 10 times more accurate. This article summarizes some of the many recollections accumulated by the author during that professional journey.

Structure determinations by x-ray diffraction methods indicate that Fe(CO)3 units are bonded to a butadiene type of residue in C8H8Fe(CO)3(I), and in (OC)3FeC8H8Fe(CO)3 (II), where the two Fe(CO)3 units are on opposite sides of the C8H8 ring. The dihedral C8H8 ring in (I) and the chair C8H8 ring in (II) are previously unknown and unsuspected geometries for cyclo-octatetraene. Crystals of (I) have symmetry Pnam, within experimental error, with four molecules in a unit cell defined by the parameters a=6.54, b=13.46, c=11.50 Å. Crystals of (II) are of symmetry P21/n, with four molecules in a unit cell which has parameters a=12.52, b=13.38, c=8.86, and β=111°. Final values of R=Σ | | F0 | — | Fc ‖/Σ | F0 | are 0.09 for (I) and 0.10 for (II) for all observed reflections. The bonding of Fe to the butadiene-like residues is discussed.
