摘要：

The title compound N-tert-butyl-N(-（2,4-dichlorobenzoyl）-N-[1-（4-chlorophenyl）- 1,4-dihydro-6-methylpyridazine-4-oxo-3-carbonyl]hydrazine [（C23H21N4O3Cl3）2·1.5H2O, Mr = 1042.60] was prepared by the reaction of 1-（4-chlorophenyl）-1,4-dihydro-4-oxo-6- methylpyridazine-3-carboxylic acid with chloroformate ethyl ester, then with N′-tert-butyl-N- （2,4-dichlorobenzoyl） hydrazine in the present of triethylamine. The crystal structure has been determined by X-ray diffraction. The crystal belongs to Monoclinic, space group P21/c, with unit cell constants a =11.4948（9）, b=12.7495（10）, c=35.854（3） ?, β =92.964（2）°, Z=4, V=5247.6（7） ?3, Dc = 1.320 Mg/m3, F（000） = 2156 , μ （MoKa）= 0.385, R = 0.0661, wR = 0.1875, for 9151 observed reflections( I >2σ（I）). The structure is a dimer linked by intermolecular hydrogen bond which can be observed between N（1）- H...O（6）, N（5）- H...O（3）. The distances are 2.068 and 2.027? respectively.
