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. 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
