The compound, C(32)H(28)N(4)O(5), which was synthesized by the reaction of 2,5-bis-(2-hydroxy-lphen-yl)-1,3,4-oxadiazole with N-benzyl-2-chloro-acetamide, lies on a twofold rotation axis which passes through the mid-point of the N-N bond and the O atom of the oxadiazole unit. The phenyl-ene and oxadiazole rings are almost coplanar [dihedral angle 1.67 (5)°]. The structure is stabilized by intra-molecular N-H⋯O and N-H⋯N hydrogen bonds.
化合物C(32)H(28)N(4)O(5)由2,5-双-(2-羟基-1-苯基)-1,3,4-恶二唑与N-苄基-2-氯乙酰胺反应合成,位于一个二重旋转轴上,该轴穿过N-N键的中点和恶二唑单元的O原子。苯环和恶二唑环几乎共面[二面角1.67 (5)°]。该结构通过分子内N-H⋯O和N-H⋯N氢键得以稳定。
