4-(4-Fluoro-phen-yl)-3-(pyridin-4-yl)-1-(2,4,6-trichloro-phen-yl)-1H-pyrazol-5-amine.

ABSTRACT: In the title compound, C(20)H(12)Cl(3)FN(4), the pyrazole ring forms dihedral angles of 47.51?(9), 47.37?(9) and 74.37?(9)° with the directly attached 4-fluoro-phenyl, pyridine and 2,4,6-trichloro-phenyl rings, respectively. Only one of the two amino H atoms is involved in hydrogen bonding. The crystal packing is characterized by N-H?N hydrogen bonds, which result in infinite chains parallel to the c axis.

(E)-Benzaldehyde (2,4,6-trichloro-phen-yl)hydrazone.

Project description:The title compound, C(13)H(9)Cl(3)N(2), was obtained from a condensation reaction of benzaldehyde and 2,4,6-trichloro-phenyl-hydrazine. The mol-ecule assumes an E configuration with the phenyl ring and trichloro-phenyl ring located on opposite sides of the C=N bond. The phenyl ring is oriented at a dihedral angle of 42.58 (12)° with respect to the tricholorophenyl ring. In the crystal, the mol-ecules are linked via N-H⋯N hydrogen bonds, forming supra-molecular chains running along the c axis. π-π stacking is present between parallel trichloro-phenyl rings of adjacent mol-ecules, the face-to-face and centroid-centroid distances being 3.369 (14) and 3.724 (2) Å, respectively.

N-(2-Methyl-phen-yl)-6-(1H-pyrazol-1-yl)pyridazin-3-amine.

Project description:The title compound, C(14)H(13)N(5), crystallizes with two crystallographically independent mol-ecules in the unit cell.
