In the crystal structure of the title compound, C(21)H(18)N(2)O(2), mol-ecules are linked through C-H⋯O inter-actions. Two symmetry-related mol-ecules form a cyclic centrosymmetric R(2) (2)(20) dimer. These dimers are further connected into chains running along the b axis.

In the title compound, C(28)H(24)ClNO(3), the dihedral angles between the central benzene ring and the indole ring system and the chlorobenzene ring are 70.81 (5) and 78.62 (5)°, respectively. The mol-ecular structure is stabilized by a weak intra-molecular C-H⋯O inter-action. In the crystal, pairs of C-H⋯O hydrogen bonds link the mol-ecules into inversion dimers with an R(2) (2)(14) motif.

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...

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 ...
متن کامل3-(4-Bromophenyl)-1-phenyl-1H-pyrazole-4-carbaldehyde
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.
