In the title compound, C(13)H(13)ClN(4)O, the dihedral angle between the aromatic rings is 33.47 (9)° and an intra-molecular N-H⋯N hydrogen bond generates an S(6) ring. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds occur, resulting in R(2) (2)(8) loops.

The reaction of 2,4-dichloro-5-(trifluoro-meth-yl)pyrimidine with 1H-pyrazole gave two structural isomers in a 1:1 ratio that were separable by chromatography. The title compound, C(8)H(4)ClF(3)N(4), was the first product to elute and was characterized in the present study to confirm that substitution by the pyrazolyl group had occurred at position 4. The mol-ecule (with the exception of the F ...

In the title compound, C(17)H(13)Cl(2)N(3), the dihedral angle between the pyrazole ring system and 4-chloro-phenyl ring is 26.1 (2)°. The C=N bond linking the two aromatic rings has an E conformation.

The title compound, C(19)H(19)N(3)O(2), is a Schiff base compound derived from 4-amino-anti-pyrine and 5-hydr-oxy-2-methyl-benzaldehyde. The mol-ecule adopts a trans configuration about the central C=N bond. There is an intra-molecular O-H⋯N hydrogen bond. Futhermore, weak C-H⋯O hydrogen bonds lead to the formation of a chain developing parallel to the b axis.

In the title compound, C(14)H(11)ClN(2)O(2), two independent mol-ecules (A and B) comprise the asymmetric unit with the main difference between them being the relative orientation of the pendent phenyl ring with respect to the fused-ring system [dihedral angles = 8.32 (8)° (A) and 28.32 (8)° (B)]. In the crystal, the A mol-ecules are connected into a linear supra-molecular chain along the a axi...
