Crystal structure and Hirshfeld surface analysis of di­iodido­{N′-[(E)-(phen­yl)(pyridin-2-yl-κN)methylidene]pyridine-2-carbohydrazide-κ(2) N′,O}cadmium(II)

In each of the two independent mol­ecules in the asymmetric unit of the title compound, [CdI(2)(C(18)H(14)N(4)O)], the N,O,N′-tridentate N′-[(E)-(phen­yl)(pyridin-2-yl-κN)methyl­idene]pyridine-2-carbohydrazide ligand and two iodide anions form an I(2)N(2)O 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.
