oa South African Journal of Chemistry - Redetermination of the structure of biferrocene

 

Abstract

The crystal structure of biferrocene, [C5H5FeC5H4]2, has been reinvestigated by X-ray diffraction methods at room temperature. Data were collected on a four-circle diffractometer equipped with graphite-crystal monochromator for Mo-?? radiation. To assess the degree of disorder, data were collected over one hemisphere, although the crystal class is known to be monoclinic. Exhaustive least-squares refinement (R = 0,066) failed to produce a model that accounts for all of the observed electron density. The unexplained peaks define a distorted five-membered ring which is recognized as the remnant of an ordered low-temperature phase.
