The unit cell of (I) viewed along a, showing the ABAB layer sequence. Intermolecular interactions at the layer interface as described in the text are represented by dashed lines. Non-H atoms are shown as 50% probability displacement ellipsoids and the H atoms involved in the C—H⋯O contacts are drawn as small spheres of arbitrary radii. Selected atoms are labelled.
