In the title compound, C12H15N2O+·C2H3O2
−, the phenoxy group is nearly perpendicular [80.73 (11)°] to the dihydropyrimidinium ring. In the crystal, O—H...O, N—H...O and C—H...O hydrogen bonds form corrugated layers parallel to the ac plane.
In the title hydrate, C19H26ClN3O4·H2O, the imidazole ring is nearly perpendicular [dihedral angle = 89.5 (1)°] to the dihydropyridine moiety. The propyl and one of the ethyl groups are disordered over two resolved sets of sites [occupancy factors 0.524 (8):0.476 (8) and 0.640 (16):0.360 (16), respectively]. In the crystal, a three-dimensional network is constructed by O—H...O, N—H...O and N—H...N hydrogen bonds involving both the main molecule and the water molecule of crystallization, as well as C—H...π(ring) interactions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
