Thakar, Amit S. published the artcileIsolation, characterization and X-ray structure determination of the Schiff base ligand: 5-methyl-2-phenyl-4-[phenyl-(4-phenyl-thiazol-2-ylamino)- methylene]-2,4-dihydro-pyrazol-3-one, Product Details of C17H14N2O2, the publication is South African Journal of Chemistry (2015), 39-44, database is CAplus.
The structure of the amine tautomer of the new Schiff base derived from 4-benzoyl-5-methyl-2-phenyl-2,4-dihydro-pyrazol- 3-one and 4-phenyl-thiazol-2-ylamine was confirmed by means of single crystal X-ray diffraction. The title compound was synthesized and crystals were grown from a mixture of dichloromethane and n-hexane (1:3). Single crystal X-ray diffraction anal. showed that the structure was primarily stabilized by strong intramol. N3-H3A···O1 hydrogen bonds [N3-H3A = 0.883(19) Å, H3A···O1 = 1.925(18) Å, N3···O1 = 2.6901(13) Å, with an angle for N3-H3A···O1 = 144.1(17) °] and this lead to the formation of a pseudo nine-membered hydrogen bonded pattern. Elemental anal., FTIR and NMR analyses was employed to characterize the crystal.
