(a) Crystal-structure fragments of L-serinium semi-maleate, (I) . The C22(12) chains are linked to each other via C(6) chains. (b) The C22(12)′ chains linked to each other via C(5) chains. The C22(12)′ chains look like springs and can be supposed to account for the interesting response of this structure to variations in pressure or temperature. Hydrogen bonds are shown as pale lines. |
