AB - The first synthetic manganese tetrazene complexes are described as a redox pair comprising anionic [Mn(N4Ad2)2]− (1) and neutral Mn(N4Ad2)2 (2) complexes (N4Ad2=[Ad‐N−N=N−N‐Ad]2−). Compound 1 is obtained in two forms as lithium salts, one as a cationic Li2Mn cluster, and one as a Mn–Li 1D ionic polymer. Compound 1 is electronically described as a MnIII center with two [N4Ad2]2− ligands. The one‐electron oxidized 2 is crystalized in two morphologies, one as pure 2 and one as an acetonitrile adduct. Despite similar composition, the behavior of 2 differs in the two morphologies. Compound 2‐MeCN is relatively air and temperature stable. Crystalline 2, on the other hand, exhibits a compositional, dynamic disorder wherein the tetrazene metallacycle ring‐opens into a metal imide/azide complex detectable by X‐ray crystallography and FTIR spectroscopy. Electronic structure of 2 was examined by EPR and XPS spectroscopies and DFT calculations, which indicate 2 is best described as a MnIII ion with an anion radical delocalized across the two ligands through spin‐polarization effects.
