Synthesis and Structure of the First Sulfur‐Bridged [1]Ferrocenophane

A sulfur atom is the smallest bridging element yet incorporated into a [1]ferrocenophane. This is demonstrated by the synthesis of the purple, crystalline [1]ferrocenophane 1 (structure depicted on the right). The 31.05(10)° tilt angle between the planes of the cyclopentadienyl rings is the largest for any iron group [n]metallocenophane.
