Crystal structure of N′-[4-(dimethylamino)benzylidene]furan-2-carbohydrazide monohydrate

Abstract

The condensation of 2-furoic hydrazide and 4-dimethyl aminobenzaldehyde in ethanol yielded a yellow solid formulated as the title compound, C14H15N3O2·H2O. The crystal packing is stabilized by intermolecular O(water)—H...O,N(carbohydrazide) and N—H...O(water) hydrogen bonds, which form a two-dimensional network along the bc plane. Additional C—H...O interactions link the molecules into a three-dimensional network. The dihedral angle between the mean planes of the benzene and the furan ring is 34.47 (6)°. The carbohydrazide moiety, i.e., the C=N—N—C=O fragment and the benzene ring are almost coplanar, with an angle of 6.75 (9)° between their mean planes.
