Crystal structure and Hirshfeld surface analysis of di-iodido-{N'-[(E)-(phen-yl)(pyridin-2-yl-κN)methylidene]pyridine-2-carbohydrazide-κ(2) N',O}cadmium(II).

In each of the two independent mol-ecules in the asymmetric unit of the title compound, [CdI(2)(C(18)H(14)N(4)O)], the N,O,N'-tridentate N'-[(E)-(phen-yl)(pyridin-2-yl-κN)methyl-idene]pyridine-2-carbohydrazide ligand and two iodide anions form an I(2)N(2)O penta-coordination sphere, with a distorted square-pyramidal geometry, with an I atom in the apical position. Both mol-ecules feature an intra-molecular N-H⋯N hydrogen bond. In the crystal, weak aromatic π-π stacking inter-actions [centroid-centroid separation = 3.830†(2)†à ] link the mol-ecules into dimers.
