1,3-Diphenyl-1H-pyrazole-4-carbaldehyde
There are four mol-ecules in the asymmetric unit of the title compound, C(16)H(12)N(2)O. The dihedral angle between the phenyl rings in the mol-ecules are 22.2 (2), 22.4 (2), 25.1 (3) and 41.9 (2)°. In the crystal, mol-ecules form dimers due to inter-molecular C-H⋯O hydrogen bonds, which result in one R(2) (2)(10) and two R(2) (1)(7) ring motifs. Weak aromatic π-π stacking [centroid-centroid se...
متن کامل1-Phenyl-1H-pyrazole-4-carbaldehyde
In the title mol-ecule, C(10)H(8)N(2)O, the five- and six-membered rings form a dihedral angle of 10.14 (9)°. The aldehyde group is almost coplanar with the pyrazole ring to which it is connected [O-C-C-C torsion angle = -179.35 (17)°]. In the crystal, inversion dimers are linked by four C-H⋯O inter-actions as the carbonyl O atom accepts two such bonds. The dimeric aggregates are linked into su...

The asymmetric unit of the title compound, C(18)H(16)N(2)O(2), contains two independent mol-ecules (A and B). In mol-ecule A, the pyrazole ring is inclined at angles of 48.86 (6) and 60.80 (6)° with respect to the two phenyl rings; the corresponding angles for mol-ecule B are 46.86 (6) and 58.63 (6)°. In the crystal, mol-ecules of type A are linked into sheets parallel to (001) via weak C-H⋯O h...
متن کامل3-(4-Bromophenyl)-1-phenyl-1H-pyrazole-4-carbaldehyde
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.
