摘要：
The structure of acylamino derivatives of 1-(2,4,6-trichlorophenyl)-4,5-dihydropyrazol-5-one was studied by X-ray diffraction. 3-Acetylamino-1-(2,4,6-trichlorophenyl)-4,5-dihydropyrazol-5-one and 3-benzoylamino-1-(2,4,6-trichlorophenyl)-4,5-dihydropyrazol-5-one exist in crystal as CH tautomers. The nature and number of acylamino groups were found to affect the nature of intermolecular hydrogen bonds in the crystals studied.
