Crystal structure of bis-{N'-[(E)-4-hy-droxy-benzyl-idene]pyridine-4-carbohydrazide-κN(1)}di-iodidocadmium methanol disolvate.

In the title compound, [Cd(C13H11IN3O2)2]·2CH3OH, which crystallizes with Z = 4 in the space group Pbcn, the Cd(II) atom is located on a twofold rotation axis and coordinated by two I(-) anions and two N atoms from the pyridine rings of the two N'-[(E)-4-hy-droxy-benzyl-idene]pyridine-4-carbohydrazide ligands. The geometry around the Cd(II) atom is distorted tetra-hedral, with bond angles in the range 94.92 (11)-124.29 (2)°. The iodide anions undergo inter-molecular hydrogen-bonding contacts with the C-H groups of the organic ligands of an adjacent complex mol-ecule, generating a chain structure along the b axis. Furthermore, an extensive series of O-H⋯O, N-H⋯O and C-H⋯O hydrogen-bonding inter-actions involving both the complex mol-ecules and the ethanol solvate mol-ecules generate a three-dimensional network.
