1,2,5-Thiadiazole 1,1-dioxides and Their Radical Anions: Structure, Properties, Reactivity, and Potential Use in the Construction of Functional Molecular Materials

This work provides a summary of the preparation, structure, reactivity, physicochemical properties, and main uses 1,2,5-thiadiazole 1,1-dioxides in chemistry material sciences. An overview all currently known structures containing 1,1-dioxide motif (including anions radical species) is provided according to Cambridge Structural Database search. The analysis bond lengths typical for neutral anion species performed, providing useful tool unambiguous assessment valence state dioxothiadiazole-based compounds based solely on structural data. Theoretical methodologies used literature describe dioxothiadiazoles are also shortly discussed, together with ‘fingerprint’ dioxothiadiazole ring reported by means various spectroscopic techniques (NMR, IR, UV-Vis). second part describes synthetic strategies leading followed discussion their electrochemistry reactivity including mainly chemical methods successful reduction forms ability form coordination compounds. Finally, magnetic properties metal complexes involving as ligands simple alkali salts d-block last section prospect other dioxothiadiazole-containing molecules perspectives possible future research directions these
