چکیده
The title compound, C(20)H(12)Cl(3)N(3)O(2), was synthesized by the reaction of 2-(2-hydroxy-phen-yl)benz[e][1,3]oxazin-4-one with 2,4,6-trichloro-phenyl-hydrazine in ethanol. The trichloro-phenyl ring is nearly perpendicular to the triazole plane [dihedral angle 80.56 (8)°], whereas the two hydroxy-phenyl rings are approximately coplanar with the triazole ring [dihedral angles of 2.79 (12) and 8.00 (14)°]. Intra-molecular O-H⋯N hydrogen bonding is observed between the hydroxy-phenyl and triazole rings.

The structure of the title compound, C(14)H(12)N(4)O(2), was determined as part of a project on the coordination chemistry of 1,2,4-triazole derivatives. In the crystal structure, one of the two benzene rings is almost coplanar with the five-membered triazole ring (mean deviation = 0.019 Å), whereas the second benzene ring is rotated by 51.973 (2)°. The two N-C-N-N torsion angles [170.365 (2) a...

Neat 3,5-dinitro-1H-1,2,4-triazole was obtained in quantitative yield from potassium 3,5-dinitro-1,2,4-triazolate and sulfuric acid. The compound was purified by sublimation in vacuo at 110 °C. Pure HDNT is a hygroscopic white solid that is impact and friction sensitive and decomposes explosively upon heating to 170 °C. However, the presence of impurities might lower the decomposition temperatu...
