Ethylenediaminium pyridine-2,5-dicarboxylate dihydrate
MetadataShow full item record
The title compound, C2H10N22+烷H3NO42-粈2O, forms a three-dimensional hydrogen-bonded framework structure in which both of the amine groups of ethyl�ediamine are protonated and participate in a total of six hydrogen-bonding inter�tions with carboxyl�e O-atom acceptors of the anions as well as the water mol�ules. The cations lie on crystallographic inversion centres and adopt extended conformations, while the anions have twofold rotational symmetry. This results in the pyridine N atom and its ortho-related CH group being disordered over two 50% occupancy sites.
