Figure 2
A packing diagram for (I)[link], showing the four catemeric connections created by acid-to-ketone hydrogen bonds (dashed lines) proceeding along chains of mol­ecules translationally related in a. All methyl­ene H atoms have been omitted for clarity. The O atoms involved in the hydrogen bonding are labelled in one of the chains; atom O3AA is at the symmetry position (x − 1, y, z). Displacement ellipsoids are drawn at the 40% probability level.
