“…The FT-IR spectra of H 2 L and its metal complexes are shown in Figure . The C–H stretching vibrational modes are frequently seen in the 3100–3000 cm –1 region. − For H 2 L, the C–H stretching vibrations were observed at 3093 and 3055 cm –1 , the in-plane bending vibration occurs in 1331, 1174, and 1126 cm –1 , and the out-of-plane bending vibrations originated at 958, 844, 764, and 671 cm –1 . The CH 3 asymmetric and symmetric stretching vibrational modes were found at 2994 and 2972 cm –1 ; in addition, the CH 2 asymmetric and symmetric stretching vibrational modes were found at 2916 and 2895 cm –1 .…”

New cobalt(II), copper(II), and zinc(II) Schiff metal complexes were synthesized by the condensation reaction of 4-nitrobenzene-1,2-diamine with 3−4-(diethylamino)-2-hydroxybenzaldehyde. Fourier transform infrared, nuclear magnetic resonance, ultraviolet−visible, electron paramagnetic resonance, and high-resolution electrospray ionization mass spectrometry and powder X-ray diffraction were used to characterize the synthesized H 2 L and its metal complexes. Conductance measurements, magnetic moment estimation, and metal estimation have all been determined and discussed. The electrochemical properties of the synthesized compounds have been determined and discussed using cyclic voltammetry. The molecular structures of H 2 L and its metal complexes have been optimized using the B3LYP functional and the 6-31G (d,p) basis set, and their parameters have been discussed. The quantum chemical properties of these synthesized compounds have been predicted through charge distribution and molecular orbital analysis. The biological properties of the synthesized compounds' antioxidant, antifungal, and antibacterial activity have been studied and discussed. Furthermore, H 2 L and its complexes have been docked with HER2associated target proteins in breast cancer.

The compound [L] was produced in the current study through the reaction of 4-aminoacetophenon with 4-methoxyaniline in the cold, concentrated HCl with 10% NaNO2. Curcumin, several transition metal complexes (Ni (II), La (III), and Hg (II)), and compound [L] were combined in EtOH to create new complexes. UV-vis spectroscopy, FTIR, AA, TGA-DSC, conductivity, chloride content, and elemental analysis (CHNS) were used to describe the structure of produced complexes. Biological activities against fungi, S. aureus (G+), Pseudomonas (G-), E. coli (G-), and Proteus (G-) were demonstrated using complexes. Depending on the outcomes of the aforementioned methods, octahedral formulas were given as the geometrical structures for each created complex.
