1,2‐Bis(ferrocenyl)‐Substituted Distibene and Dibismuthene: SbSb and BiBi Units as π Spacers between Two Ferrocenyl Units

Abstract

Pi in the sky: 1,2‐bis(ferrocenyl)distibene and 1,2‐bis(ferrocenyl)dibismuthene derivatives, where two bulky ferrocenyl units are bridged by a SbSb and BiBi π spacer, have been synthesized as a new family of novel d–π conjugated systems. Their molecular structures, spectroscopic behavior, and electrochemical properties reveal the SbSb and BiBi units to be effective π‐electron spacers.
