3-(4-Chloro­phen­yl)-5-(4-eth­oxy­phen­yl)-4,5-dihydro-1H-pyrazole-1-carbothio­amide ethanol monosolvate

The asymmetric unit of the title compound, C₁₈H₁₈ClN₃OS·C₂H₅OH, comprises a pyrazoline derivative and an ethanol solvent mol­ecule. In the mol­ecule of the pyrazoline derivative, the pyrazole ring adopts an envelope conformation with the C atom bearing the eth­oxy­phenyl substituent as the flap. The dihedral angle between the benzene rings is 74.22 (7)°. The eth­oxy group is coplanar with the attached benzene ring [C—O—C—C_meth­yl = 175.50 (11)° and r.m.s. deviation = 0.0459 (1) Å for the nine non-H atoms]. In the crystal, the pyrazoline mol­ecules are linked by N—H...O_eth­oxy hydrogen bonds into chains along the c axis and are further linked with the solvent ethanol mol­ecules by N—H...O_ethanol and O_ethanol—H...S hydrogen bonds. C—H...π inter­actions are also present.
