4-[(2,4-Difluorophenyl)hydrazinyl-idene]-3-methyl-5-oxo-4, 5-dihydro-1H-pyrazole-1-carbothioamide

Abstract

In the title compound, C11H9F2N 5OS, the pyrazole ring forms a dihedral angle of 16.42 (6)° with the benzene ring. Intramolecular N - H⋯O hydrogen bonds generate two S(6) ring motifs. In the crystal, an R 22(8) ring motif is formed by a pair of intermolecular N - H⋯S hydrogen bonds. Intermolecular C - H⋯F hydrogen bonds further link the molecules into a three-dimensional network. © Fun et al. 2011.
