(a) The six-membered ring built from π–π stacking and C—H⋯π interactions (dashed lines), with centroid (0, 0, 0). Dotted lines indicate O—H⋯O interactions. H atoms not involved in hydrogen bonding have been omitted. [Symmetry code: (i) y, −x + y, −z + 2]. (b) An ab projection of the crystal structure of (I), showing the [001] channels. |
