(E)-3-[3-(4-Bromo-phen-yl)-1-phenyl-1H-pyrazol-4-yl]-1-(2,4-dichloro-phen-yl)prop-2-en-1-one.

ABSTRACT: In the title mol-ecule, C(24)H(15)BrCl(2)N(2)O, 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 mol-ecule exists in a trans conformation with respect to the acyclic C=C bond. In the crystal, mol-ecules 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?? inter-actions.

(2E)-1-(2,4-Dichloro-phen-yl)-3-[3-(4-nitro-phen-yl)-1-phenyl-1H-pyrazol-4-yl]prop-2-en-1-one.

Project description:In the title compound, C(24)H(15)Cl(2)N(3)O(3), the C=C double bond is E configured. The 1-phenyl-1H-pyrazole moiety is roughly planar (r.m.s. deviation of all fitted non-H atoms = 0.0780?Å), but the mean planes of the two components are inclined at an angle of 9.95?(7)°. The mean plane defined by the non-H atoms of the 1H-pyrazole ring encloses angles of 9.95?(7), 24.54?(6) and 43.02?(6)° with the mean planes of the different benzene rings. In the crystal, C-H?O contacts are present and result in the formation of a double-layer two-dimensional network lying parallel to (110). The shortest inter-centroid distance between two aromatic systems is 3.5455?(7)?Å and is apparent between two pyrazole systems. Further ?-? inter-actions are manifest between a pair of 4-nitro-phenyl rings [centroid-to-centroid distance = 3.6443?(7)?Å] and a pair of 2,4-dichloro-phenyl rings [centroid-to-centroid distance = 3.7797?(7)?Å].
