Synthesis, structural characterization and biological studies of Ni(II), Cu(II) and Fe(III) complexes of hydrazone derived from 2-(2-(2,2-dimethyl-4,6-dioxo-1,3-dioxan-5-ylidene)hydrazinyl)benzoic acid

Synthesis, Characterization, Antimicrobial, Density Functional Theory, and Molecular Docking Studies of Novel Mn(II), Fe(III), and Cr(III) Complexes Incorporating 4-(2-Hydroxyphenyl azo)-1-naphthol (Az)

“…In general, high-spin Fe(III) complexes have magnetic moment values of around 5.90 μ B with no possibility of orbital contribution, while low-spin complexes (S = 1/2) have values close to 1.70 μ B. 57 The μ eff value for FeAz 2 is found to be 1.84 μ B , which is compatible with a return to the d 5 (t 2g 5 ) configuration; 58 Table 1. This suggests that the complex has an octahedral geometry with Fe(III) as its core.…”

“…3,4 There has been a significant amount of research done on the production of metal(II) complexes of azo compounds, as well as their biological activity. 5,6 Because their azo group possesses powerful medicinal properties, azo dyes are advantageous chelating agents for a variety of metal ions, 7,8 due to the azo group of these dyes. In addition to this, it has been demonstrated that azo metal complexes can be beneficial as metal anticorrosion agents and as thermally stable optical storage devices, 9,10 There is an urgent need for new metal-based compounds that can prevent the development of hazardous germs that have become worldwide spread.…”

The inhibition performance of a novel iron (III), copper (II), and nickel (II) complexes with Schiff base ligand derived from salicylaldehyde and p–phenylene diamine on Polyvinyl chloride photodegradation

“…The electronic absorption spectra of the prepared ligand (L) and related metal ion complexes of Fe(III), Cu(II), and Ni(II) were recorded at 10 − 3 M concentration in DMF solution at room temperature over the wavelength range of 200-800 nm (Fig. 1) [37]. The ligand (L) exhibits two intense absorption bands.…”

Bimetallic bis-Aroyldihydrazone-Isatin Complexes of High O=V(IV) and Low Cu(II) Valent Ions as Effective Biological Reagents for Antimicrobial and Anticancer Assays

“…One of the most versatile transition elements is copper (as a very suitable and cheap element), with structural and chemical potential for various proposes [ 17 ]. Currently, many organic derivatives of copper (II) hydrazone-based organometallic reagents have been synthesized for many biological studies, such as Cu 2+ , Ni 2+, and Fe 3+ complexes derived from the dioxanylidene hydrazinyl benzoic acid ligand, as highly reactive antimicrobial reagents [ 18 ]. Furthermore, Samy and Shebl reported the antitumor activity of newly designed N , O -hetero pincer chelating hydrazone complexes of copper(II), nickel(II), and cobalt(II) ions within docking studies against hepatocellular carcinoma [ 19 ].…”
