organic compounds
The molecules of the title compound, C13H14O4, the condensation product of vanillin and acetylacetone, are hydrogen bonded into a linear chain arising from interaction between the hydroxy group of one molecule and the acetyl group of an adjacent molecule.
organic compounds
The title compound, C36H50O3·C2H4O2, crystallizes with acetic acid solvent molecules in a 1.1 stoichiometric molar ratio. The molecules are connected by intermolecular O—HO hydrogen bonds, resulting in zigzag chains running along the [101] axis.
organic compounds
The title compound, C18H14O3, also known as 1,2-dihydrotanshinquinone, contains a four-ring system. No classical hydrogen bonds are found in the structure.
organic compounds
The molecules of the title compound, C16H12O4, are linked by hydrogen bonds involving the two hydroxy and carbonyl O atoms, forming a three-dimensional network.
organic compounds
In the title compound, C18H14O3·0.5H2O, also known as dihydrotanshinone hemihydrate, the molecular skeleton is a nearly planar. The two molecules in the asymmetric unit are linked by O—HO hydrogen bonds involving the carbonyl groups and the solvent water molecule, forming moieties which are, in turn, linked via intermolecular π–π stacking interactions into a two-dimensional sheet.
