In the title compound, C21H18N6·H2O, two 4,4′-dipyridyl­amine groups are linked by a methyl­ene C atom, which sits on a twofold axis. The lattice water mol­ecule is located slightly off a twofold axis, and is therefore disordered over two positions. In the crystal, the organic mol­ecules and the water mol­ecule are linked by O—H⋯N hydrogen bonds. The organic mol­ecules exhibit extensive offset face-to-face π–π inter­actions to symmetry equivalents [centroid–centroid distances = 3.725 (3) and 4.059 (3) Å].
