Progress in 1, 5-diamino-1H-tetrazole and its derivatives

The progress in the salts and complexes of 1, 5-diamino-1H-tetrazole (DAT) were described and reviewed. The optimized synthesis processes were emphasized with the precursor of diaminoguanidine chloride as raw materials. The DAT can easily forms salt resulting from reacting with strong acid, and easily forms six energetic complexes resulting from coordinating in six DAT molecules with perchlorate. All of these DAT compounds are sensitive to mechanic stimulus, and possess good explosive properties. Therefore, DAT compounds have potential applications in the high energy density materials.
