Figure 1
A centrosymmetric hydrogen-bonded dimer composed of two asymmetric units of (I

), shown with the atom-numbering scheme. Only the major (68%) contributor to the disordered carboxyl group is shown. Ellipsoids are set at the 20% probability level and H atoms are shown as spheres of arbitrary radii.
