Abstract: The title urea derivative crystallizes as a monohydrate, C19H27N3O2·H2O. The central C3N grouping is almost planar (r.m.s. deviation = 0.0092 Å), and the amide and pyridine groups are substantially twisted out this plane [dihedral angles = 62.80 (12) and 34.98 (10)°, respectively]. Supramolecular double chains propagating along the b-axis direction feature in the crystal packing whereby linear chains sustained by N-H
O hydrogen bonds formed between the amide groups are linked by helical chains of water molecules (linked by O-HO hydrogen bonds). The H atom that participates in these water chains is disordered over two positions of equal occupancy. The double chains are connected into a two-dimensional array by C-HO contacts and the layers stack along the a axis.
