N'-(4-Bromo-benzyl-idene)quinoline-8-sulfonohydrazide.

ABSTRACT: In the title compound, C(16)H(12)BrN(3)O(2)S, the dihedral angle between the planes of the almost planar (r.m.s. deviation = 0.0263 Å) quinoline group and the bromo-phenyl group is 87.4 (1)°. The torsion angle of the central S-N-N-C bridge is 144.8 (2)°. The amino group has an intra-molecular contact to the quinoline N atom. The structure is stabilized by one N-H⋯O and two C-H⋯O inter-molecular hydrogen bonds.
