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

ABSTRACT: 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.
