Synthesis And Single Crystal X-Ray Diffraction Study Of a Schiff Base Derived From 4-Acylpyrazolone And 2-Aminophenol

摘要

The title compound, (Z)-1-(3-chlorophenyl)-4[1{(2hydroxyphenyl)amino}propylidene]-3-methyl-1H-pyrazol-5(4H)-one was synthesized by refluxing compound 1-(m-chlorophenyl)-3-methyl-4-propionyl-5-pyrazolone, with 2-aminophenol in ethanol. The compound crystallizes in the orthorhombic crystal system with space group Pca2_1 having unit cell parameters: a = 26.2993(8), b = 7.0724(2) and c = 18.7170(5)? .The structure contains two crystallographically independent molecules, A, and, B, in the asymmetric unit cell. The crystal structure was solved by direct method using single crystal X-ray diffraction data collected at room temperature and refined by full-matrix least-squares procedures to a final R- value of 0.049 for 5207 observed reflections.
