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.

The five-membered dihydro-pyrazole ring in the title compound, C(10)H(9)F(3)N(2)O, is approximately planar (r.m.s. deviation 0.111 Å for all non-H atoms) and its phenyl substituent is aligned at an angle of 14.7 (2)°. Adjacent mol-ecules are linked by N-H⋯O and O-H⋯N hydrogen bonds, generating ribbons running along the b axis of the monoclinic unit cell.

In the title compound, C(16)H(11)BrN(2)O, the phenyl and chloro-benzene rings are twisted out of the mean plane of the pyrazole ring, forming dihedral angles of 13.70 (10) and 36.48 (10)°, respectively. The carbaldehyde group is also twisted out of the pyrazole plane [the C-C-C-O torsion angle is 7.9 (3)°]. A helical supra-molecular chain along the b axis and mediated by C-H⋯O inter-actions is ...

The asymmetric unit of the title compound, C16H11BrN2O, contains two independent mol-ecules with slightly different geometries. The 4-bromo-benzene ring forms dihedral angles of 26.0 (2) and 39.9 (7)° with the pyrazole ring in the two mol-ecules while the phenyl ring is oriented at 19.7 (5) and 7.3 (0)° with respect to the pyrazole ring.

In the title compound, C(16)H(11)ClN(2)O, the chloro-substituted phenyl ring is disordered over two positions with refined site occupancies of 0.503 (2) and 0.497 (2). The dihedral angle between the pyrazole and phenyl rings is 7.93 (7)°. The pyrazole ring also forms dihedral angles of 24.43 (9)° and 28.67 (9)° with the disordered chloro-substituted benzene ring. In the crystal, mol-ecules are ...
