abstract The asymmetric unit of the title compound, C19H18N2O3, comprises a whole organic dipyridinone molecule plus a water molecule of crystallization. The planes of the pyridinone rings are approximately perpendicular with the plane of the central aromatic ring [dihedral angles = 80.68 (8) and 83.65 (8)degrees]. The C-O bond of the hydroxy group subtends an angle of 31.71 (10)degrees with the plane through the central aromatic ring. The crystal packing is mediated by the presence of several O-H center dot center dot center dot O hydrogen-bonding interactions and while the water molecules form a C-2(1)(4) chain parallel to the c axis of the unit cell, the pendant hydroxy groups are engaged in O-H center dot center dot center dot O=C hydrogen bonds described by a C (1)(1)(12) graph-set motif which runs parallel to the a axis.
