(a) A view along [110] of PAXNIL02 (Palmer et al., 2010). (b) Views of the two (001) layers (axes [10] and [110]) in which different parts of the molecule (cyclo-diaspartic acid) pack. The –CH2COOH groups form a layer with approximate symmetry p; the central C4H4N2O2 rings (two stereocenters) are in a layer of approximate symmetry c211. |
