title: 3-(4-Chloro-phen-yl)-5-(4-eth-oxy-phen-yl)-4,5-dihydro-1H-pyrazole-1-carbothio-amide ethanol monosolvate.
abstract: The asymmetric unit of the title compound, C18H18ClN3OS·C2H5OH, comprises a pyrazoline derivative and an ethanol solvent mol-ecule. In the mol-ecule of the pyrazoline derivative, the pyrazole ring adopts an envelope conformation with the C atom bearing the eth-oxy-phenyl substituent as the flap. The dihedral angle between the benzene rings is 74.22 (7)°. The eth-oxy group is coplanar with the attached benzene ring [C-O-C-Cmeth-yl = 175.50 (11)° and r.m.s. deviation = 0.0459 (1) Å for the nine non-H atoms]. In the crystal, the pyrazoline mol-ecules are linked by N-H⋯Oeth-oxy hydrogen bonds into chains along the c axis and are further linked with the solvent ethanol mol-ecules by N-H⋯Oethanol and Oethanol-H⋯S hydrogen bonds. C-H⋯π inter-actions are also present.
