Synthesis, Structure, Photophysics, and Excited‐State Redox Properties of the Novel Luminescent Tetranuclear Acetylidocopper(<scp>I</scp>) Complex [Cu₄(μ‐dppm)₄(μ₄‐η¹,η²‐CC‐)](BF₄)₂

Abstract

A strong reducing power in the excited state is just one of the features of the tetranuclear copper(I) complex 1. It contains an acetylide dianion bridging four copper atoms in both η1 and η2 bonding modes and exhibits long-lived luminescence. The central framework of the structure is shown on the right.
