Lithium shares electrons with organic cathode scaffolds—sometimes. A new paper from the Wagner Research Group, led by graduate student Fahmida Islam and featured on the cover of ACS Organometallics, synthesizes a series of 1,4-diazine radical-bridged lithium complexes.
Their investigation using electron paramagnetic resonance shows that the unpaired electron is distributed across both the lithium atoms and the 1,4-diazine, but in the case of the π-extended phenazine system, the unpaired electron remains confined to the 1,4-diazine. This work establishes π-extension as a synthetic handle for modulating metal-ligand covalency in radical systems.
