The title compound, C(26)H(23)F(2)NO(3), was synthesized by the reaction of 2-(4-fluoro-benzyl-idene)-4-methyl-3-oxo-N-phenyl-penta-namide and 4-fluoro-benzaldehyde. The dihedral angles between the mean plane through the pyrrolidine ring (nearly planar; maximum deviation of 0.145 Å for the C atom bearing the hydroxy group) with the phenyl and benzene rings are 37.22 (7), 51.88 (7) and 87.64 (9)°, respectively. The pyyolidine ring is near coplaner, with max offset of 0.145 A for C19 atom.\uff09 In the crystal, mol-ecules are linked by pairs of O-H⋯O hydrogen bonds into inversion dimers, which are further assembled into chains parallel to the b axis by weak C-H⋯O hydrogen bonds.
标题化合物C(26)H(23)F(2)NO(3)是由2-(4-氟亚苄基)-4-甲基-3-氧代-N-苯基戊酰胺与4-氟苯甲醛反应合成的。通过吡咯烷环的平均平面(几乎为平面;带有羟基的C原子的最大偏差为0.145 Å)与苯环和苯基环之间的二面角分别为37.22 (7)°、51.88 (7)°和87.64 (9)°。吡咯烷环接近共面,C19原子的最大偏移为0.145 Å。在晶体中,分子通过O-H⋯O氢键对连接成反演二聚体,这些二聚体通过弱C-H⋯O氢键进一步组装成平行于b轴的链。
