Figure 3
The hydrogen-bonded framework generated by the pseudo-tetrahedral supramolecular connections in (I[link]). Mol­ecules A and B are shown by open and filled circles, respectively, representing the centres of gravity of the mol­ecules. Double carboxylic acid hydrogen bonds are depicted by solid lines. The connections via motifs e (and g) and f are denoted by dotted and dashed lines, respectively. The selected four-, six- and eight-membered rings are indicated by diamonds, asterisks and triangles, respectively.
