Abstract

In the title compound, [CdI2(C13H11N3O2)(2)]center dot 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 CdII atom is distorted tetrahedral, with bond angles in the range 94.92 (11)-124.29 (2)degrees. 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 center dot center dot center dot O, N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen-bonding interactions involving both the complex molecules and the ethanol solvate molecules generate a three-dimensional network.
