(E)-4-[(1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)iminomethyl]-2-methoxyphenyl 4-bromobenzenesulfonate

Abstract

Key indicators: single-crystal X-ray study; T = 294 K; mean (C-C) = 0.003 Å; R factor = 0.025; wR factor = 0.059; data-to-parameter ratio = 13.2.In the title compound, C 25 H 22 BrN 3 O 5 S, the central benzene ring makes dihedral angles of 4.41 (10), 67.09 (9) and 62.05 (10) , respectively, with the pyrazolone, bromobenzene and terminal phenyl rings. The dihedral angle between the pyrazolone and phenyl rings is 57.75 (11) . In the crystal, two pairs of C-HÁ Á ÁO hydrogen bonds link the molecules into inversion dimers. A weak intramolecular C-HÁ Á ÁO hydrogen bonds is also observed. Related literature ExperimentalCrystal data
