3-Methyl-5-phenoxy-1-phenyl-1H-pyrazole-4-carbaldehyde
In the title compound, C(17)H(14)N(2)O(2), the pyrazole ring makes dihedral angles of 73.67 (4) and 45.99 (4)°, respectively, with the adjacent phenyl and phen-oxy rings. In the crystal, there are no classical hydrogen bonds, but a weak C-H⋯π inter-action is observed.

In the title compound, [Fe(C(5)H(5))(C(15)H(11)N(4)O(4))], the dinitro-phenyl and cyclo-penta-dienyl rings make dihedral angles of 53.61 (6) and 23.11 (9)°, respectively, with the pyrazole unit. The two cyclo-penta-dienyl rings are in an eclipsed conformation. The crystal structure is stabilized by inter-molecular C-H⋯O inter-actions, which link mol-ecules into chains parallel to the b axis.
متن کامل3-Benzyl-6-benzylamino-1-methyl-5-nitro-1,2,3,4-tetrahydropyrimidine
In the title compound, C(19)H(22)N(4)O(2), the tetra-hydro-pyrimidine ring adopts an envelope conformation (with the N atom connected to the benzyl group representing the flap). This benzyl group occupies a quasi-axial position. The two benzyl groups lie over the tetra-hydro-pyridimidine ring. The amino group is a hydrogen-bond donor to the nitro group.
متن کامل(E)-1-Methyl-5-(3-methyl-4-chlorophenoxy)-3-trifluoromethyl-1H-pyrazole-4-carbaldehyde O-acetyloxime
In the title mol-ecule, C(15)H(13)ClF(3)N(3)O(3), the pyrazole and benzene rings form a dihedral angle of 77.6 (3)°. In the crystal, mol-ecules related by translation along the a axis are linked into chains via C-H⋯O hydrogen bonds. The crystal packing is stabilized further by weak π-π [centroid-centroid distance = 3.734 (6) Å] and dipole-dipole inter-actions [C⋯O = 3.174 (2) Å].
متن کاملMethyl 3-[3-(ethoxycarbonyl)thioureido]-1H-pyrazole-5-carboxylate
The title compound, C(9)H(12)N(4)O(4)S, was proven to be the product of the reaction of methyl 5-amino-1H-pyrazole-3-carboxyl-ate with ethyl isothio-cyanato-carbonate. All non-H atoms of the mol-ecule are planar, the mean deviation from the least squares plane being 0.048 Å. The intra-molecular N-H⋯O bond involving the NH-group, which links the thio-urea and pyrazole fragments, closes a six-mem...
