Cyanuric triazide reacts with several transition metal precursors, extruding one equivalent of N 2 and reducing the putative diazidotriazeneylnitrene species by two electrons, which rearranges to N -(1′ H -[1,5′-bitetrazol]-5-yl)methanediiminate (biTzI 2− ) dianionic ligand, which ligates the metal and dimerizes, and is isolated from pyridine as [M(biTzI)] 2 Py 6 (M = Mn, Fe, Zn, Cu, Ni). Reagent scope, product analysis, and quantum chemical calculations were combined to elucidate the mechanism of formation as a two-electron reduction preceding ligand rearrangement.
