(E)-3-[3-(4-Bromophenyl)-1-phenyl-1H-pyrazol-4-yl]-1-(2,4-dichlorophenyl) prop-2-en-1-one

Abstract

In the title molecule, C24H15BrCl2N 2O, the dihedral angles betwen the pyrazole ring and its N-bonded phenyl (A) and C-bonded bromo-benzene (B) rings are 10.34 (16) and 40.95 (15) , respectively. The dihedral angle between rings A and B is 56.89 (17) . The title molecule exists in a trans conformation with respect to the acyclic C=C bond. In the crystal, molecules are linked into inversion dimers by pairs of C - H?O hydrogen bonds, generating R 2 2(14) loops. The crystal structure is further consolidated by C - H?? interactions.
