Projection along a of the (a,9b,7c) approximant unit cell of the structure of 2. The structure can be regarded as an assembly of stacked blocks (e.g. bloc I and II), each two molecules thick. The C-(COH)2 groups form ribbons running along the b axis (highlighted by purple lines), with their undulation being out of phase between adjacent blocks. In contrast, the long hydro­carbon chains (highlighted by purple lines) exhibit in-phase undulations both within a block and between successive blocks.
