“…[20] The ligаnd's IR spectrum relative to the IR spectra of metal complexes reveals the band at 1660 cm À1 for imine group of the free ligand shifted to 1601-1604 cm À1 in the complexes, indicating the participation of the imine nitrogen atom in coordination. [16,21,22] The band at 3047 cm À1 that corresponded to the free ligand's υ(OH) functional group disappeared, indicating replacement of proton during complex formation.

A new series of solid Cr(II), Co(II), Cu(II), Pd(II), and Cd(II) chelates of the 1-((E)-(2-mercaptophenylimino)methyl)naphthalen-2-ol (H 2 L) Schiff base ligand were synthеsized and chаracterized by diffеrent аnalytical and spectroscopic tеchniques. The results revealed the geometry around central metal ion to be tetrahedral for Cr 2 L 2 , Co 2 L 2 , Cu 2 L 2 , and Cd 2 L 2 complexes and square planar geometry around Pd 2 L 2 complex. 3D modeling of the ligand and its metal complexes was obtained using DFT/B3LYP method with LANL2DZ basis set. Also quantum-mechanical properties like molecular orbitals and molecular energies were calculated. The Cu nano complexes were prepared in different media Spinacia oleracea (SO), Corchorus olitorius (CO), Coriandrum sativum (CS), Eruca sativa (ES), and Anethum graveolens (AG) extract in EtOH. The particle size of the nano coordination Cu complexes depends on the high concentration of reducing agent present in the green leaf extract. The nature of the newly nano sizеd Cu complexes prepared in different media as crystalline or amorphous and particles size was determined by X-ray diffraction (XRD); scanning electron microscope (SEM). The Cu nano complexes are characterized by spectroscopic and thermal analysis techniques before heating and after heating upon 200 C. The Cu nano complexes were showed an antitumor activity towards hepatocellular carcinoma cell line (HepG-2). The antitumor data revealed that the Cu nano complex prepared in CS/EtOH (IC 50 $ 4.9 μg ml À1 ) has antitumor activity nearly to the activity of cis-platin (IC50 $ 1.143 μg ml À1 ). The DNA cleavage study showed that the ability for the screened Cu nano complex prepared in CS/EtOH to cleavage DNA. Therefore, it may be used as antitumor drugs in vivo to prevent the DNA replication in the tumor cells and to suppress the cancer for further increasing. Docking studies of the ligand and its Cu(II) complex showed good binding energy score ranging from (À4.73 to À5.98 kcal mol À1 ).

A new Schiff base derived from o-hydroxy aromatic aldehyde, namely 1-[(3-hydroxyphenylamino) methylene]-naphtalen-2-one (L), was synthesized and characterized by X-ray crystallographic technique. It is then evaluated as inhibitor on the corrosion of mild steel XC48 in a 1M hydrochloric acid solution. The study was carried out using weight loss, polarization, electrochemical impedance spectroscopy and Quantum chemical. At constant temperature, the corrosion rate decreases with increasing the inhibitor content. A maximum inhibition efficiency of 78.3 % was obtained at 10 -3 M. However, the increase in temperature leads to an increase in the corrosion rate of steel. Calculation and estimation of thermodynamic parameters E a , ∆H°a ds , ∆S°a ds , and ∆G°a ds help in determining the inhibition mechanism of the Schiff base. It was found that Schiff base acted as mixed type inhibitor with predominant cathodic inhibition and adsorbs according to Langmuir adsorption isotherm model. Morphological surface aspect has been investigated using optical microscope. Quantum chemical calculations study corroborates experimental results.
