3-(3-Chloro-2-hydroxyphenyl)-1-phenyl-1H-pyrazole-4-carbaldehyde
In the title compound, C(16)H(11)ClN(2)O(2), the pyrazole ring makes dihedral angles of 11.88 (13) and 22.33 (13)° with the 3-chloro-2-hy-droxy-benzene group and phenyl rings, respectively. The phenolic hy-droxy group forms an intra-molecular O-H⋯N hydrogen bond with the imine N atom of the pyrazole unit. The formyl group is virtually coplanar with the pyrazole ring [dihedral angle = 4.5 (19)°]...

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 ...
متن کامل3-(4-Methoxyphenyl)-1-phenyl-1H-pyrazole-4-carbaldehyde
Four independent mol-ecules comprise the asymmetric unit of the title compound, C(17)H(14)N(2)O(2). The central pyrazoline ring is flanked by an N-bound benzene ring and a C-bound meth-oxy-substituted benzene ring. The greatest difference between the independent mol-ecules is found in the relative orientations of the benzene rings with the range of dihedral angles being 23.59 (6)-42.55 (6)°. In...
