The mol-ecule of the title compound, C(10)H(12)N(2)O(2), adopts a trans configuration with respect to the C=N bond. The dihedral angle between the phenyl ring and the hydrazine carboxylic acid mean plane is 25.23 (9)°. In the crystal structure, mol-ecules are linked into chains by N-H⋯O hydrogen bonds and C-H⋯π inter-actions.

The development of new environmentally friendly energetic compounds with reasonable detonation performance and safety is a long-term target in energetic materials research. A new energetic eco-friendly salt of hydrazine 5,5'-bitetrazole-1,1'-diolate (HA·BTO) is developed based on the reaction of 1H,1'H-5,5'-bitetrazole-1,1'-diolate (BTO) with hydrazine hydrochloride (HA·HCl), and fully characte...

One of the most challenging problems in small molecule activation is the development of a homogeneous catalyst for converting dinitrogen into ammonia at ambient temperatures and atmospheric pressure. A catalytic cycle based on molybdenum that converts dinitrogen into ammonia has been reported. However, a well defined iron based system for the conversion of dinitrogen into ammonia or hydrazine h...

The asymmetric unit of the title compound, C(19)H(15)N(3)O(2), contains two mol-ecules, both of which show an E conformation of the imine bond. The dihedral angles between the phenyl rings in the phenyl-hydrazine groups are 86.09 (6) and 83.41 (5)° in the two mol-ecules. The 4-nitrobenzene rings show torsion angles of 4.4 (2) and 10.9 (2)° from the two C=N-N planes. In the crystal, C-H⋯π inter-...

In the title compound, C(26)H(19)N(3)O, the dimethyl-ene hydrazine (-C=N-N=C-) unit is approximately planar, the torsion angle around the N-N bond being 162.2 (6)°. The phenyl and benzoyl-phenyl rings at one end of the hydrazine unit are aligned at angles of 9.5 (5) and 88.5 (4)°, respectively, with respect to the hydrazine unit, whereas the benzene ring at the other end is twisted by an angle ...

The title compound, 3-amino-5-methyl-5-(4-pyrid-yl)imid-azol-idine-2,4-dione, C(9)H(10)N(4)O(2), was obtained by reaction of 5-methyl-5-(4-pyrid-yl)hydantoin with hydrazine. It crystallizes as a racemate in the tetra-gonal space group I4(1)/a with one mol-ecule in the asymmetric unit. The dihedral angle between the pyridine ring and the five-membered hydantoin ring is 47.99 (3)° In the crystal ...
