Abstract :
In each of the two independent molecules in the asymmetric unit of the title compound, [CdI2(C18H14N4O)], the N,O,N′-tridentate N′-[(E)-(phenyl)(pyridin-2-yl-κN)methylidene]pyridine-2-carbohydrazide ligand and two iodide anions form an I2N2O pentacoordination sphere, with a distorted square-pyramidal geometry, with an I atom in the apical position. Both molecules feature an intramolecular N—H⋯N hydrogen bond. In the crystal, weak aromatic π–π stacking interactions [centroid–centroid separation = 3.830 (2) Å] link the molecules into dimers.
