چکیده
The title mol-ecule, C17H15ClN2O2, is L-shaped with the 4-chloro-benzyl-idene ring almost coplanar with the planar pyrazolidine ring (r.m.s. deviation = 0.020 Å), making a dihedral angle of 4.83 (17)°. The 4-meth-oxy-phenyl ring is almost normal to the mean plane of the pyrazolidine ring and the 4-chloro-benzyl-idene ring, with dihedral angles of 87.36 (17) and 89.23 (16)°, respectively. The pyrazolidine ring occurs in the betaine form with a Z configuration for the exocyclic C=N bond. In the crystal, C-H⋯O and C-H⋯π inter-actions generate ribbons of mol-ecules along [1-10].
