The Schiff base used to make the title compound was synthesized from tris(hydroxymethyl)aminomethane and 5-nitrosalicylaldehyde. The ligand (0.23 g, 0.85 mmol) was dissolved in ethanol (25 ml) and several drops of aqueous sodium hydroxide were added to raise the pH of the solution to about 8.5. Zinc acetate (0.09 g, 0.43 mmol) was then added and the mixture heated for 5 h. The solvent was removed and the product recrystallized from DMSO to yield faint yellow blocks of (I). The water in (I) was presumably incorporated from the atmosphere.
The carbon-bound H atoms were placed at calculated positions (C–H = 0.95–0.99 Å), and they were included in the refinement in the riding model approximation with Uiso(H) = 1.2Ueq(C). The hydroxy and water H atoms were located in a difference Fourier map, and were refined with a distance restraint (O–H = 0.84±0.01 Å); their Uiso values were freely refined.
A previous study (Ali et al., 2006) reported the structure of the complex ion found in the title compound as a bis-pyridine solvate. The use of DMSO as solvent yielded the title trihdrate (I) (Fig. 1). Two deprotonated Schiff-base ligands chelate through their phenoxy oxygen atoms, imino nitrogen and hydroxyl oxygen atoms (Table 1). The hydroxy groups of the ligands are engaged in extensive hydrogen bonding with the the uncoordinated water molecules to lead to a three-dimensional network (Table 2).
For the same metal complex as a pyridine solvate, see: Ali et al. (2006).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |

A previous study (Ali et al., 2006) reported the structure of the complex ion found in the title compound as a bis-pyridine solvate. The use of DMSO as solvent yielded the title trihdrate (I) (Fig. 1). Two deprotonated Schiff-base ligands chelate through their phenoxy oxygen atoms, imino nitrogen and hydroxyl oxygen atoms (Table 1). The hydroxy groups of the ligands are engaged in extensive hydrogen bonding with the the uncoordinated water molecules to lead to a three-dimensional network (Table 2).
