Abstract
The title compound, C15H14N2O5·CH3OH, displays an E conformation about the azomethine double bond [C=N = 1.277 (2) Å] and the benzene rings are inclined to one another by 18.28 (9)°. An intramolecular O—H⋯O hydrogen bond occurs between the para-OH group and one of the meta-O atoms of the 3,4,5-trihydroxybenzylidene group. In the crystal, the components are linked into a three dimensional network by O—H⋯O, O—H⋯N and C—H⋯O hydrogen bonds.
