Abstract :
In the title compound, [Cd(C13H11IN3O2)2]·2CH3OH, which crystallizes with Z = 4 in the space group Pbcn, the CdII 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 CdII 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.
