چکیده
The asymmetric unit of the title compound, C(19)H(18)N(2)O(3), comprises a whole organic dipyridinone mol-ecule plus a water mol-ecule 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)°]. The C-O bond of the hy-droxy group subtends an angle of 31.71 (10)° with the plane through the central aromatic ring. The crystal packing is mediated by the presence of several O-H⋯O hydrogen-bonding inter-actions and while the water mol-ecules form a C(2) (1)(4) chain parallel to the c axis of the unit cell, the pendant hy-droxy groups are engaged in O-H⋯O=C hydrogen bonds described by a C(1) (1)(12) graph-set motif which runs parallel to the a axis.
