Tetramerization with α‐thienyl migration to give 2 and subsequent cleavage of the P‐P bonds of the dimer with sodium afforded access, starting from 1 , to a biphospholyl dianion which is isoelectronic with α‐sexithienyl. Its further derivatization yielded a W‐ and a Mo‐complex, whose X‐ray structure analyses afforded important information about the electronic structure of the chain.
