(Top) Contributing resonance structures for 1, with bond line drawing depicting the resultant extended π conjugation. (Bottom) Contributing resonance structures result from an admixture of ILCT excited states into the electronic ground state, and create bond asymmetry in the dithiolene chelate, which is observed in the bond metrics of the X-ray structure of 1.25
