1,5-Diamino-1H-1,2,3,4-tetrazole

Synthesis, structural investigation and thermal properties of a novel manganese complex Mn2(DAT)2Cl4(H2O)4 (DAT=1,5-diaminotetrazole)

“…Similar amino group geometries are observed in the structure of molecular DAT [51]. Most of the bond lengths and angles for the DAT ligand in Mn 2 (DAT) 2 Cl 4 (H 2 O) 4 are similar to those corresponding to unbound DAT, except for the elongation of the N1-C1 bond by 0.008 Å and the N6-C1 bond by 0.006 Å.…”

“…X-ray structure As shown in Table 1 4 compared with those in the molecular crystal of DAT [51] are given in Table 2. The hydrogen bond lengths and angles are listed in Table 3.…”

Theoretical study on novel nitrogen-rich energetic compounds of bis(amino)-azobis(azoles) with tetrazene unit

“…Furthermore, the same trend exists in each group of those bonds in the rings, in that they become more homogeneous when nitrogen content increases. Finally, for all the compounds (with C-45d as an exception), the H 2 N−C bond or N−(N0N) bond (corresponding to the N−NH 2 of the reactant molecules) is never the longest bond, which is quite different from the condition in 1,5-diaminotetrazole, because in this molecule, the N−NH 2 (1.383 Å) is the longest [62]. This should result from the π conjugation between the N0N and the five-membered ring.…”

“…In 1,5-diaminotetrazole, the values of N−N−NH 2 and C−N−NH 2 are quite close (125.13°and 126.02°, respectively) [62], while this phenomenon is absent in 5,5'-bis(amino)-1,1'-azobis(tetrazoles). The bond angle of N−N−(N0N) becomes bigger and that of C−N−NH 2 becomes smaller, but the sum of them changes little, which suggests that this alteration is mainly caused by the rotation of the five-membered rings in their molecule planes.…”

Synthesis, structural investigation, thermal decomposition mechanism and sensitivity properties of an energetic compound [Cd(DAT)6](ClO4)2 (DAT=1,5-diaminotetrazole)

“…2). Hydrogen bonds can also be formed between DAT molecules [38]. It may be caused by the hydrogen-bond interactions in the crystal structure of the title coordination compound.…”
