acylhydrazinocabonylpyridazinone%crystal structure%synthesis
The title compound N-[1-(4-chlorophenyl)-1,4-dihydro-4-oxe-6-methylpyridazine-3-carbonyl]-N'-benzoylhydrazine was prepared by the reaction of 1-(4-chlorophenyl)-1,4-dihydro-4-oxe-6-methylpyridazine-3-carboxylic acid with chloroformate ethyl ester and benzoyl hydrazine in the presence of triethylamine. The crystal structure The crystal is monoclinic, space group P2t/c, with unit cell parameters a=13.296(3),b=17.155(3), c=17.459(3)A, β=98.959(4), Z=4, V=3934(1) A3, Dc=1.371g/cm3, F(000)=1688,μ (MoKa)=0.226 mm-1, R=0.0495, wR=0.1348 for 3345 observed reflections (Ⅰ＞2 σ(Ⅰ)). The hydrogen bonsd N(3)-H…O(1),N(7)-H…O(4),and N(8)-H…O(2)can be observed.
