In order to assist in the interpretation of the D 5 h molecular structure of [4 5 ] (1,2,3,4,5)ferrocenophane ( 1 ) obtained from x‐ray crystallographic analysis, a hypothetical hydrocarbon C 30 H 40 ( 2 ) was derived from 1 by removing the iron atom and subjected to geometry optimization by molecular mechanics. A stable D 5 conformer was found for 2 , which has a g + g − g + helical bridge conformation and a ring–ring distance almost identical with that in 1 and ferrocene itself. Optimization of a perhydrogenated hydrocarbon model gave a highly strained C 1 structure.
