A new record tilt angle [32.4(2)°] is present between the planes of the cyclopentadienyl ligands in the [1]boraferrocenophane 1 . This compound is the first [1]ferrocenophane containing a first row element in the bridge. Ring‐opening polymerization of 1 leads to cyclic oligomers and insoluble polymer 2 .
