Hydrogen-bond images of Berkecoumarin. (a) The two different hydrogen bonds within the Berkecoumarin structure. Hydrogen bonds are displayed by both red and neon green dotted lines. (b) Highlighted in neon green is the C(10) helical chain formed by the hydrogen bond of the phenolic alcohol group of one mol­ecule to the tertiary alcohol group of an adjacent species. (c) The hydrogen bond (red dotted line) of the tertiary alcohol group to the coumarin carbonyl group. Mol­ecules of similar color schemes are `above' each other.
