4-[2-(2-Meth-oxy-phen-yl)hydrazinyl-idene]-3-methyl-5-oxo-4,5-dihydro-1H-pyrazole-1-carbothio-amide.

ABSTRACT: In the title mol-ecule, C(12)H(13)N(5)O(2)S, a bifurcated intra-molecular N-H?O(O) hydrogen bond forms two S(6) ring motifs. The benzene ring forms a dihedral angle of 14.36?(11)° with the pyrazole ring. In the crystal, pairs of N-H?S hydrogen bonds form centrosymmetric dimers, generating R(2) (2)(8) ring motifs, which stack along the b axis.
