Öğe Crystal structure and Hirshfeld surface analysis of diiodido(N '-[(E)-(phenyl)(pyridin-2-yl-kappa N)methyl-idene]pyridine-2-carbohydrazide-kappa N-2 ',O}-cadmium(II)(2019) Atioğlu, Zeliha; Afkhami, Farhad Akbari; Akkurt, Mehmet; Khandar, Ali Akbar; Choquesillo-Lazarte, DuaneIn 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-?N)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 ?–? stacking interactions [centroid–centroid separation = 3.830?(2)?Å] link the molecules into dimers.
