(E)-4-[(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 17.13 (13), 39.83 (13) and 58.37 (13)°, respectively, with the pyrazolone ring, the bromo-benzene ring and the terminal phenyl ring. In the crystal structure, the packing is stabilized by a weak non-classical inter-molecular C-H⋯O hydrogen bond which links the mol-ecules into a chain propagating in [100].
