In the title complex, [Ni(C17H16N2O5)]·2H2O, the NiII ion is four-coordinated by two azomethine N and two phenolato O atoms of the tetradentate Schiff base ligand in a slightly distorted square-planar geometry. In the six-membered ring containing the metal, the azomethine N atoms and the three C atoms of the connecting 1,3-diaminopropane-2-ol, all atoms except the metal are disordered over two sets of sites with an occupacy ratio of 0.566 (3):0.434 (3). The central C atom of the major component is significantly out of the mean plane of the remaing atoms while the conformation of this ring in the minor component is noticeably different. In the crystal, O-HO hydrogen bonds involving the lattice water molecules and the hydroxy groups are observed.
