Coop mode : The reaction of azobenzene with a redox‐active bis(imino)pyridine vanadium dinitrogen complex resulted in NN bond cleavage and formation of the bis(imido) derivative (see picture). Similar reactivity was observed with O 2 and S 8 to yield the analogous terminal bis(oxides) and bis(sulfides), respectively. Studies of the electronic structure of the vanadium products show that bond cleavage involves reducing equivalents from the metal and the ligands.
