Abstract
In the title compound, [Fe(C(5)H(5))(C(20)H(21)N(2)O(4))], the pyrrolidine ring exhibits an envelope conformation with the spiro-C atom deviating from the plane of the remaining four atoms. The pyrrolidine ring is almost perpendicular to the indolinone ring [dihedral angle = 87.52 (7)°]. The structure is stabilized by an intra-molecular O-H⋯N hydrogen bond and by inter-molecular C-H⋯O and N-H⋯O inter-actions.
摘要
在标题化合物[Fe(C₅H₅)(C₂₀H₂₁N₂O₄)]中，吡咯烷环呈信封式构象，螺碳原子偏离其余四个原子所在平面。吡咯烷环与吲哚酮环几乎垂直[二面角 = 87.52 (7)°]。该结构通过分子内O—H⋯N氢键以及分子间C—H⋯O和N—H⋯O相互作用得以稳定。
