5-Hydroxy-1-(3-hydroxy-2-naphthoyl)-3,5-dimethyl-2-pyrazoline

Abstract

In the title molecule, C16H16N2O3, intramolecular O—H...O hydrogen bonds influence the molecular conformation. Intermolecular O—H...O hydrogen bonds [O...O = 2.922 (2) Å] link the molecules into centrosymmetric dimers. Weak intermolecular C—H...O interactions assemble these dimers into layers parallel to the bc plane.
