Group 11 metals have important applications in biology and catalysis.  Ligation of these metals with amidinates has been studied for various applications, especially ALD, but studies involving their reactivity are limited, especially with copper.  Our group has focused on stabilizing Cu(I) to form a dinuclear framework, Cu2(amid)2, amid = 2,6-dimethylphenylformamide, which is identical to the gold analog.  The reactivity and photophysical properties of Cu2(amid)2 will be shown including the reversible quenching of O2 as well as insertion and redox chemistry to produce polynuclear metal clusters.  The molecular and electronic structure of di- and trinuclear mixed-valent copper complexes will be discussed using EPR spectroscopy as well as quantum calculations.
