Tetrazene tetrazolyl

Performance tests consisted of loading DBX-1 as a transfer charge in U.S. Army M55 stab detonators. Standard M55 detonators consist of three separate explosive layers, pressed sequentially into a metal detonator cup as shown in Figure 6. The first layer is 15 mg of the stab initiation mix (NOL-130) it is a combination of lead azide, lead styphnate, barium nitrate, antimony sulfide, and tetrazene [l-(5-tetrazolyl)-3-guanyltetra-zene hydrate], pressed at 70,000 psi. The second layer is 51 mg of transfer charge, lead azide, pressed at 10,000 psi. Lastly, the third layer is 19 mg of output charge, RDX, pressed at 15,000 psi.

Hoffmann etal. [26] suggested the structural formula (la) for tetrazene, i.e. l-guanyl-4-nitrosoaminoguanyltetrazene. The correctness of this formula was later questioned by Patinkin, Horwitz and Lieber [27]. The synthesis of tetrazene by the action of tetrazolediazonium hydroxide (II) on aminoguanidine salts (III) at 0°C, suggested that tetrazene has the structure of l-(5-tetrazolyl)-4-guanyltetrazene hydrate (I) ...

Tetrazene or tetrazolyl guanyltetrazene hydrate (C2H8N10O) (2.5) was first prepared by Hoffmann and Roth in 1910 by the action of a neutral solution of sodium nitrite on aminoguanidine salts. In 1921, Rathsburg suggested the use of tetrazene in explosive compositions.

If we adopt Roman numerals for tetrazene , then the name will be (Tetrazolyl-5 ), guanyl.l, IV-tetrazene orGuanyl(tetrazolyl-5f). IV, 1-tetrazene. The figure 5 which follows the name of the tetrazoly radical, signifies that the position 5 of the tetrazolyl is connected to the tetrazene. 

F.R. Benson, p 9, calls it 4-Tetrazolyl-5-tetra-zene-guanyl-1, while the Germans called it either l-Guanyl-4-tetrazolinyliden-(5)-tetrazen or 1-Guanyl-4-tetrazolyl-(5)-tetrazen. None of these names are simple and comprehensive...
