5-Methyl-N′-(3-nitrobenzylidene)isoxazole-4-carbohydrazide
The mol-ecule of the title compound, C(12)H(10)N(4)O(4), displays an E configuration about the C=N bond. The dihedral angle between the benzene and isoxazole rings is 1.36 (5)° and the mol-ecular conformation is stabilized by the an intra-molecular C-H⋯N hydrogen bond. In the crystal structure, centrosymmetrically related mol-ecules are connected by pairs of N-H⋯O hydrogen bonds into dimers, wh...

In the title compound, C24H20N4O2, the pyrazole ring makes dihedral angles of 47.57 (10)° and 30.56 (11)° with its N-bound and C-bound phenyl groups, respectively. The C-N-N-C group that links the two carbonyls has a torsion angle of 81.5 (2)°. The torsion angles between the carbonyl groups and their adjacent pyrazole and phenyl rings are 125.89 (19) and 164.22 (17)°, respectively. In the cryst...

In the title compound, C16H18ClN3O, the cyclo-hexane ring adopts a distorted chair conformation. In the crystal, pairs of mol-ecules are linked by N-H⋯O hydrogen bonds into inversion dimers, forming R 2 (2)(10) ring motifs. These dimers are connected through C-H⋯N hydrogen bonds into chains along the a axis, forming layers parallel to (101).

In the title compound, C(18)H(15)ClN(6)O(3), the 1,2,3-triazole ring forms dihedral angles of 15.64 (5) and 57.50 (5)° with the two benzene rings. The dihedral angle between the two benzene rings is 72.26 (5)°. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds into chains propagating along the b axis. A short O⋯C contact of 2.9972 (13) Å is observed.
متن کامل(E)-N′-Benzylidene-5-methylisoxazole-4-carbohydrazide
The mol-ecule of the title compound, C(12)H(11)N(3)O(2), is approximately planar with an r.m.s. deviation of 0.0814 Å from the plane through all the non-H atoms. The dihedral angle formed by the benzene and isoxazole rings is 6.88 (16)°. The mol-ecular conformation is stabilized by an intra-molecular C-H⋯N hydrogen bond, forming an S(6) ring, and the mol-ecule displays an E configuration with r...
