The Schiff base mol-ecule of the title compound, C(15)H(14)N(2)O(4)·C(3)H(7)NO, adopts a trans configuration with respect to the C=N double bond; the Schiff base itself is nearly planar (r.m.s. deviation 0.20 Å). The amido N atom is a hydrogen-bond donor to the dimethyl-formamide solvate mol-ecule. One of the hydr-oxy groups forms an intra-molecular hydrogen bond to the N atom of the C=N double bond, whereas the other forms an inter-molecular hydrogen bond to the carbonyl group.
标题化合物C(15)H(14)N(2)O(4)·C(3)H(7)NO的席夫碱分子相对于C=N双键呈反式构型;席夫碱本身近乎平面(均方根偏差0.20 Å)。酰胺基N原子是二甲基甲酰胺溶剂化物分子的氢键供体。其中一个羟基与C=N双键的N原子形成分子内氢键,而另一个则与羰基形成分子间氢键。
