Abstract: In the title compound, C23H17N3·0.5C2H6O, two pyrazole molecules are bridged by one ethanol molecule through N-HO and O-HN hydrogen bonds. The ethanol solvent molecule is located on a mirror plane. These trimolecular units are linked by C-HN, N-HO and hydrogen bonds involving the nitrile groups and ethanol OH as acceptors and C-H stacking interactions between phenyl groups.
