In the title compound, C(10)H(11)N(3)O(2), the nitro group is essentially coplanar with the aromatic ring [dihedral angle = 3.4 (3)°] and forms an intra-molecular N-H⋯O hydrogen bond with the amine group. In the crystal, weak aromatic C-H⋯O and C-H⋯N hydrogen bonds link the mol-ecules. Weak aromatic ring π-π inter-actions [minimum ring centroid-centroid separation = 3.9841 (16) Å] are also present.

1-(4-Isopropyl-phen-yl)-5-(4-methoxy-phen-yl)pyrazolidin-3-one.

Acta Crystallogr Sect E Struct Rep Online 2008 Apr 16;64(Pt 5):o855. Epub 2008 Apr 16.

Department of Applied Chemistry, College of Science, Nanjing University of Technology, Nanjing 210009, People's Republic of China.

In the mol-ecule of the title compound, C(19)H(22)N(2)O(2), the pyrazolidinone ring has an envelope conformation, with the C atom attached to the 4-methoxy-phenyl ring displaced by 0.354 (3) Å from the plane of the other ring atoms. The 4-iso-propyl-phenyl ring is oriented with respect to the 4-meth-oxy-phenyl ring at a dihedral angle of 88.94 (3)°. Intra-molecular C-H⋯N hydrogen bonds result in the formation of two planar five-membered rings, which are oriented with respect to the adjacent 4-isopropyl-phenyl and 4-meth-oxy-phenyl rings at dihedral angles of 4.05 (3) and 0.50 (3)°, respectively. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers.
