(E)-3-[(1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)imino-meth-yl]phenyl 4-bromo-benzene-sulfonate.

ABSTRACT: In the title compound, C(24)H(20)BrN(3)O(4)S, the central benzene ring makes dihedral angles of 24.55?(8), 49.52?(12) and 59.65?(7)°, respectively, with the pyrazolone ring, the bromo-benzene ring and the terminal phenyl ring. The packing is stabilized by weak non-classical inter-molecular C-H?O=C hydrogen bonds that form inversion-related dimers.

Project description:With respect to the aliphatic planar five-membered ring (r.m.s. deviation = 0.011?Å) of the title compound, C(15)H(13)N(3)O(2)S, the phenyl ring is aligned at 6.9?(1)° and the phenyl-ene ring at 2.4?(1)°, so that the three rings are nearly coplanar.

In the crystal, C-H?O contacts connect the mol-ecules into chains along the b axis and give rise to a C(1) (1)(14)C(1) (1)(14) and a R(2) (2)(12) pattern on different levels of graph-set analysis. The shortest inter-centroid distance between two centroids was found at 4.2074?(11)?Å between the two five-membered heterocycles.
