==Structure and bonding==
The carbon–carbon bond distances are 1.40&nbsp;Å within the five-membered rings, and the Fe–C bond distances are 2.04&nbsp;Å. 
 [[X-ray crystallography]] (in the monoclinic space group)At room temperature down to 164K,  [[X-ray crystallography]] points to the Cp rings being in a staggered conformation due to imposed molecular centrosymmetric symmetry in the monoclinic space group.<ref>{{Cite journal|last=Eiland|first=Philip Frank|last2=Pepinsky|first2=Ray|date=1952-10-01|title=X-RAY EXAMINATION OF IRON BISCYCLOPENTADIENYL|url=http://dx.doi.org/10.1021/ja01139a527|journal=Journal of the American Chemical Society|volume=74|issue=19|pages=4971–4971|doi=10.1021/ja01139a527|issn=0002-7863}}</ref> Below 110 K, ferrocene crystallizes in an orthorhombic crystal lattice in which the Cp rings are ordered and eclipsed.<ref>{{Cite journal|last=Seiler|first=P.|last2(contracted; show full){{commons category|ferrocene}}
