摘要：
The title compound (C20H21N3O4, Mr = 367.40) has been synthesized and its crystal structure was determined by single-crystal X-ray diffraction. The crystal is of orthorhombic, space group P212121 with a = 7.5143(15), b = 13.901(3), c = 18.545(4) , V = 1937.1(7) 3, Z = 4, Dc = 1.260 g/cm3, μ = 0.089 mm-1, F(000) = 776, the final R = 0.0616 and wR = 0.0912. X-ray diffraction reveals that the molecule adopts an E configuration about the central C=N double bond. The intermolecular O–H…O hydrogen bond stabilizes the crystal structure by causing the formation of a supramolecular architecture.
