| مستخلص: |
The naphthoquinone unit of the title compound, C13H8O3, is essentially planar, with an r.m.s. deviation of 0.013 Å for the non-H atoms. The essentially linear propargyl group is tilted by ca 113° relative to the naphthoquinone plane. In the crystal, molecules are linked via a pair of O--H...O hydrogen bonds, forming an inversion dimer. The dimers are further linked via pairs of C--H...O hydrogen bonds into a tape structure along [201]. No π-π stacking is observed in the present case as it could be expected for naphthoquinone derivatives. [ABSTRACT FROM AUTHOR] |
