(4Z)-4-[(2-Chloro-anilino)(phen-yl)methyl-idene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one.

ABSTRACT: The title compound, C(23)H(18)ClN(3)O, exists in an enamine-keto form with the amino group involved in an intra-molecular N-H?O hydrogen bond. The five-membered ring is nearly planar, the largest deviation being 0.0004?(7)?Å, and makes dihedral angles of 16.62?(6), 41.89?(5) and 71.27?(4)° with the phenyl rings. In the crystal, weak C-H?O hydrogen bonds link the mol-ecules into supra-molecular chains along the b axis.

The title compound, C(23)H(18)ClN(3)O, exists in an enamine-keto form with the amino group involved in an intra-molecular N-H⋯O hydrogen bond. The five-membered ring is nearly planar, the largest deviation being 0.0004 (7) Å, and makes dihedral angles of 16.62 (6), 41.89 (5) and 71.27 (4)° with the phenyl rings. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules into supra-molecular chains along the b axis. ...[more]
