Figure 8
Carboxyl–carboxyl dimers involving an anti conformer and the lone pair of a carbonyl group (`carbonyl dimer'). The C and O atoms not belonging to the interacting carboxyl groups are shown in light blue, Cl and Ge atoms are shown in green and dark green, respectively. (a) AS-S dimer (WOKPOC). (b) AS-A dimer (NEWXAO). (c) AA-S dimer involving two fumaric acid molecules (KACNAD). (d) AA-A dimer (DMOXEA01). |
