title: (2E)-1-(3,5-Di-hydroxy-phen-yl)-3-(4-meth-oxy-phen-yl)prop-2-en-1-one.
abstract: In the title compound, C16H14O4, the benzene rings are inclined to one another by 4.91 (7)°. The conformation about the C=O and C=C bonds is trans and cis, respectively. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, forming inversion dimers with an R 2 (2)(14) ring motif. The dimers are linked via O-H⋯O and C-H⋯O hydrogen bonds, forming undulating two-dimensional networks lying parallel to (10-1). These networks are linked by further C-H⋯O hydrogen bonds, forming a three-dimensional structure.
