4-[2-(4-Bromophenyl)hydrazinylidene]-3-methyl-5-oxo-4,5-dihydro-1H-pyrazole-1-carbothioamide

In the title compound, C11H10BrN5OS, the approximately planar pyrazole ring [maximum deviation = 0.014 (2) Å] forms a dihedral angle of 5.49 (13)° with the benzene ring. An intramolecular N—H...O hydrogen bond generates an S(6) ring motif. In the crystal, molecules are linked through intermolecular N—H...S and N—H...O hydrogen bonds, forming a two-dimensional network parallel to (100). A short Br...Br contact of 3.5114 (6) Å is also observed
