In the title compound, C15H12I2N2O4·CH3OH, the hydrazone molecule exists in an E conformation with respect to the C=N bond. The dihedral angle between the rings is 11.9 (2)°. There is one intramolecular O—H⋯N hydrogen bond in the hydrazone molecule. In the crystal, the hydrazone and methanol molecules are linked through O—H⋯O and N—H⋯O hydrogen bonds and C—H⋯O interactions to form two-dimensional networks lying parallel to (001).

A mixture of 2-hydroxy-3,5-diiodobenzaldehyde (0.374 g, 1 mmol) and 4-hydroxy-3-methoxybenzohydrazide (0.182 g, 1 mmol) in 30 ml of ethanol containing few drops of acetic acid was refluxed for about 1 h. On cooling to room temperature, a solid precipitate was formed. The solid was filtered and then recrystallized from methanol. Colourless crystals, suitable for X-ray
were obtained by slow evaporation of a solution of the title compound in methanol.Hydrogen atoms H2, H3, and H5 were located in a difference Fourier map and were freely refined. The remaining H-atoms were positioned geometrically and refined using a riding model: O–H = 0.82 Å, C–H = 0.93 and 0.96 Å for CH and CH3 H atoms, respectively, with Uiso(H) = k × Ueq(O,C), where k = 1.5 for OH and CH3 H-atoms, and k = 1.2 for all other H-atoms.

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell esds are taken into account in the estimation of distances, angles and torsion angles |
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. |

In recent years, hydrazone compounds have attracted much attention due to their syntheses and crystal structures (Hashemian et al., 2011; Lei, 2011; Shalash et al., 2010). As a continuation of our work on such compounds (Li, 2011a,b), the author reports herein on the crystal structure of the new title hydrazone compound.
The title compound (Fig. 1), contains a N'-(2-hydroxy-3,5-diiodobenzylidene)-4-hydroxy-3-methoxybenzohydrazide molecule and a methanol solvent molecule. The hydrazone molecule exists in a trans or E conformation with respect to the C7═N1 bond. The dihedral angle between the (C1–C6) and (C9–C14) benzene rings of the hydrazone molecule is 11.9 (2)°. There is one O–H···N intramolecular hydrogen bond in the hydrazone molecule (Table 1).
In the crystal, the hydrazone and methanol molecules are linked through O–H···O and N–H···O hydrogen bonds and C-H···O interactions (Table 1), to form a two-dimensional network lieing parallel to the ab plane (Fig. 2).
