The exceptional reactivity of the azide group makes organic azides a highly versatile family of compounds in chemistry and the material sciences. One of the most prominent reactions employing organic azides is the regioselective copper (I)-catalyzed Huisgen 1,3-dipolar cycloaddition with alkynes yielding 1,2,3-triazoles.Azides have proven to be useful precursors to amines in organic syntheses. This report describes an improvement of the diazotransfer reaction and the first example of a regioselective azide reduction of compounds containing multiple azides. The use of a specific ratio of solvents and zinc chloride as a catalyst resulted in a more efficient diazotransfer reaction capable of delivering >90% ...3 High-Yield MLPs for Investors to Buy Now...PAA Investors looking for high levels of income generally go for asset classes such as real estate investment trusts, or REITs, consume...Azide Radicals.

Note 1.Azide-Alkyne Cycloadditions, a.k.a. “Click” chemistry. An interesting and useful application of organic azides that hasn’t yet made it into introductory organic chemistry textbooks (but likely will in the near future) is a process technically called the “copper-catalyzed azide-alkyne cycloaddition“, but more commonly just called the “alkyne-azide click reaction”.Sodium azide, or NaN3, is found in a wide range of industrial and laboratory applications.

That's all it says. My understanding of why this is valid is that this gives a formal charge of (0) ( 0) for every atom, as opposed to averaging out to that. I suppose the second form makes sense, as it's a lower formal charge on the central atom.
