The current world record for the largest tilt angle in a [1]ferrocenophane is held by complex 1 ; no [1]metallocenophanes have been prepared with a bridge smaller than the sulfur atom here (I. Manners et al. Angew. Chem. Int. Ed. Engl. 1995 , 34 , 1506). The greater the ring strain in metallocene derivatives, the more readily they polymerize giving compounds like 3 , which is formed from 2 by desulfurization with phosphane. Since the metal atoms in these polymers are arranged in a regular sequence, interesting material properties are anticipated.
