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...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 ([C19H15ClN4O3]2·C2H5OH, Mr =811.67) has been determined by X-ray crystal structural analysis. The crystal is monoclinic, space group P21/c, with unit cell parameters a=13.296(3), b=17.155(3), c=17.459(3)?,β=98.959(4), Z=4, V=3934(1) ?3, Dc=1.371g/cm3, F(000)=1688, μ(MoKα)=0.226 mm-1, R=0.0495, wR=0.1348 for 3345 observed reflections (I >2σ(I)). The hydrogen bonds N(3)－H…O(1) , N(7)－H…O(4), and N(8)－H…O(2) can be observed.展开更多

The crystal is orthorhombic with space group P2 12 12 1, a=6.154(4), b=17.199(8), c=22.180(3) , V=2347.6 3, D c=1.32 g/cm 3, F(000)=984, μ=1.5 cm -1 , Z =4, and final R =0.075 and R w =0.080 for 1417 reflections (I≥3σ(I)) . The X ray diffraction analysis revealed that the structure of the title compound s similar to that of its parent phosphine and the pyranose and 4, 6 O benzylidene rings remain distorted chair conformations.展开更多
