Crystal structure of bis­{N′-[(E)-4-hy­droxy­benzyl­idene]pyridine-4-carbohydrazide-κN (1)}di­iodidocadmium methanol disolvate

In the title compound, [Cd(C(13)H(11)IN(3)O(2))(2)]·2CH(3)OH, 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-hy­droxy­benzyl­idene]pyridine-4-carbohydrazide ligands. The geometry around the Cd(II) atom is distorted tetra­hedral, with bond angles in the range 94.92 (11)–124.29 (2)°. The iodide anions undergo inter­molecular hydrogen-bonding contacts with the C—H groups of the organic ligands of an adjacent complex mol­ecule, 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 inter­actions involving both the complex mol­ecules and the ethanol solvate mol­ecules generate a three-dimensional network.
