Abstract
In the title compound, C(18)H(20)N(2)O(3), a potential bidentate N,O-donor Schiff base ligand, the benzene rings are inclined at an angle of 12.25 (19)°. The mol-ecule has an E conformation about the C=N bond. One of the ethyl groups is disordered over two positions, with a refined site-occupancy ratio of 0.55 (1):0.45 (1). An intra-molecular O-H⋯N hydrogen bond makes an S(6) ring motif. In the crystal, pairs of O-H⋯O hydrogen bonds link mol-ecules, forming inversion dimers with R(2) (2)(8) ring motifs.
摘要
在标题化合物C₁₈H₂₀N₂O₃中，它是一种潜在的双齿N,O供体席夫碱配体，苯环间呈12.25 (19)°的夹角。分子围绕C=N键呈E构象。其中一个乙基在两个位置上无序，精制的位点占有率比为0.55 (1):0.45 (1)。分子内O-H⋯N氢键形成一个S(6)环模式。在晶体中，O-H⋯O氢键对连接分子，形成具有R₂²(8)环模式的反演二聚体。
