(2E)-2-{[3-Methyl-5-(2-naphthyloxy)-1-phenyl-1H-pyrazol-4-yl]methylidene} -hydrazinecarbothioamide monohydrate

Abstract

In the title compound, C22H19N5OSH 2O, the naphthalene ring system and the benzene ring [dihedral angle = 85.19 (8)°] make dihedral angles of 87.02 (9) and 14.41 (10)°, respectively, with the pyrazole ring. The mean plane through the 2-methylenehydrazinecarbothioamide group [C - N - N - C(=S) - N; maximum deviation = 0.022 (1) Å] is slightly twisted from the pyrazole ring [dihedral angle = 5.60 (11)°]. In the crystal, molecules are linked by N - H···S, N - H···O, O - H···S, O - H···N and C - H···S hydrogen bonds into sheets parallel to the ab plane. π-π interactions are also observed [centroid-to-centroid distances = 3.7778 (12) and 3.7010 (12) Å].
