Examples of the eight catemer types identified in the CSD. The C and O atoms not belonging to the interacting carboxyl groups are shown in light blue. The white and red dots mark the position of the connected carboxylic groups in the catemeric chain. The red asterisks mark the carboxyl groups used for naming the catemer. The light blue spheres indicate that the molecule has been truncated for visualization purposes. (a) SS-S homo-catemer (XONNET); (b) SA-S homo-catemer (ACETAC07); (c) AS-A homo-catemer (GIMRAW); (d) AA-A homo-catemer (DMOXBA01); (e) SS-A·AS-S hetero-catemer (ROZHEU); (f) SS-A·AA-S hetero-catemer (WOKPOC); (g) SA-A·AS-S hetero-catemer (MEKLOE).
