    Abstract

    The asymmetric unit of the title compound, C15H15N3O3�0.5H2O, comprises two 2-{[(4-iminiumyl-3-methyl-1,4-dihydropyridin-1-yl)methyl]carbamoyl}benzoate zwitterions (A and B) and a water molecule. The dihedral angles between the pyridine and phenyl rings in the zwitterions are 53.69 (10) and 73.56 (11)� in A and B, respectively. In the crystal, molecules are linked by N—H� � �O, O— H� � �O, C—H� � �O and C—H� � ��(ring) hydrogen bonds into a three-dimensional network. The crystal structure also features �–� interactions involving the centroids of the pyridine and phenyl rings [centroid–centroid distances = 3.5618 (12) A ° in A and 3.8182 (14) A ° in B].
