چکیده
In the title compound, [Fe(C(5)H(5))(C(21)H(20)NO(5))], the pyrrolidine and cyclo-penta-none rings exhibit a twist conformation. The pyrrolidine ring is almost perpendicular to the cyclo-penta-none ring, making a dihedral angle of 81.91 (6)°. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯N hydrogen bond and C-H⋯O inter-actions. The crystal structure is stabilized by inter-molecular C-H⋯O inter-actions.
