Supporting information
A mixture of N'-(3-pyridylmethylene)benzohydrazide (3 mmol) and sodium methoxide (3 mmol) and bismuth iodide(1 mmol) in absolute ethanol (15 ml) was heated under reflux with stirring for 5 h and then filtered.The resulting clear colourless solution was diffused diethyl ether vapor at room temperature for 16 days, after which large colourless block-shaped crystals of the title complex suitable for X-ray diffraction analysis were obtained.
All H-atoms were positioned geometrically and refined using a riding model, with C—H = 0.96 Å (methylene) or 0.93 Å (aromatic),0.82 Å (hydroxyl) and Uiso(H) =1.2Ueq(C).

Special details top 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. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Schiff bases have been known as effective ligands for metal ions in the preparation of dyes for many years, liquid crystals and powerful corrosion inhibitors. Furthermore, they are used in the mechanism of many biochemical processes (Lindoy et al., 1976). We report here the synthesis and crystal structure of the title compound (I).
The molecular structure of (I) is shown in Fig.1. The values of the geometric parameters in (I) are normal (Allen et al., 1987) (Table 1). In the crystal structure, there exist two intermolecular N—H···I and O—H···N hydrogen bonds (Table 2). As seen in Fig.2, the molecules are linked into two-dimensional network.
