摘要

Polyynediyl bridged systems have attracted attention for more than two decades, with early synthetic efforts complemented more recently by experimental and computational investigations of electronic structure.~([1]) Polyynediyl complexes serve as models of the linear carbon allotrope carbyne,~([2]) and permit investigations of intramolecular electron transfer (ET) reactions and mixed-valence (MV) characteristics.~([1, 3]) The highly delocalised electronic structures often associated with [{L_nM}{μ-(C≡C)_x}{ML_n}]) complexes has also led to consideration of their potential applications in molecular electronics.~([4]) Although impressively long polyynediyl complexes are known,~([2]) the greatest concentration of work has focused on the properties of diynediyl-bridged (μ-C≡CC≡C) d~6/d~6 transition metal complexes, which have been synthesised, characterised, and investigated in their various electrochemically accessible redox states.~([1, 3, 5-12])
