A DFT study on Dichloro{(E)-4-dimethylamino-N′-[(pyridin-2 yl)methylidene-κN]benzohydrazide-κO}M2+ (M=Zn, Cu, Ni and Co) complexes: Effect of the metal over association energy and complex geometry

The molecular geometry of (E)-4-dimethylamino-N′-[(pyridin-2-yl)methylidene- N]benzohydrazide (C15H16N4O) complexed with M2+ (M=Zn, Cu, Ni, Fe, Mn, Ca and Co) ions were calculated, using density functional theory (B3LYP) with 6-31G(d, p) basis set. Vibrational frequencies were computed in order to v...
