“…The molar conductance values of the complexes in DMSO fall in the range of 1.65 to 4.34  -1 cm 2 mol -1 indicating that they are essentially non-electrolytes in DMSO. Although some dissociation of the complexes seems to occur, the conductance values are much lower than that expected for a 1:1 electrolyte in this solvent [19] . Table 3 shows also the magnetic susceptibility data and as it is observed, all the complexes has diamagnetic natures.…”

A new nitrogen sulphur Schiff base has been prepared from the condensation 1-(pyridin-4-yl)ethanone with 2-methylbenzyl hydrazinecarbodithioate. The ligand was reacted with Ni(II), Cd(II) and Zn(II) metal salts to form newcoordinated complexes. The new 2-methylbenzyl (2Z)-2-[1-(pyridin-4-yl)ethylidene]hydrazinecarbodithioate ligand and the new metal complexes were characterized via various physico-chemical and spectroscopic techniques and based on the data analysis the metal complexes are expected to be octahedral in geometry. The Schiff bases and their complexes were screened for antimicrobial and cytotoxic activities. [Cd(NS)2] displays strong activity against the bacteria strains and cytotoxicity while the other compounds shows moderate and weak activity.

“…The broad bands appeared in the region 3540–3422 cm −1 in spectra of both complexes correspond to the stretching vibrations of OH of ligand, coordination water and hydration water molecules in Cu (II) and Rh (III) complexes [28,29] . Indeed, these results were confirmed by the existence of bands between 1383 and 1349 cm −1 assigned to the deformation vibration of OH bond of water molecules.…”

“…The broad bands appeared in the region 3540-3422 cm À 1 in spectra of both complexes correspond to the stretching vibrations of OH of ligand, coordination water and hydration water molecules in Cu (II) and Rh (III) complexes. [28,29] Indeed, these results were confirmed by the existence of bands between 1383 and 1349 cm À 1 assigned to the deformation vibration of OH bond of water molecules. The middle bands that appeared at 644 cm À 1 in the Cu (II) complex (Figure 2 (a)) and 673 cm À 1 in the Rh (III) complex (Figure 2 (b)) confirmed the presence of coordination H 2 O in the structures of the metal complexes.…”

Two novel binuclear complexes of Cu (II) and Rh (III) with Bis [4‐hydroxy‐6‐methyl‐3‐{(1E)‐N‐[2‐(ethylamino) ethyl] ethanimidoyl}‐2H‐pyran‐2‐one] (L) were prepared and characterized by elemental analysis, electrospray ionization‐mass spectrometry (ESI‐MS), conductivity, nuclear magnetic resonance (NMR), Fourier transform infrared spectroscopy (FT‐IR), ultraviolet‐visible spectrophotometry, fluorescence, thermogravimetric analysis ( TGA), scanning electron microscopy (SEM), energy dispersive X‐ray spectroscopy (EDX) and cyclic voltammetry (CV). The spectral data indicate that the ligand binds the metal ions via the oxygen atom of the phenolic group, the nitrogen atoms of the azomethine and NH groups. These characterizations suggested the formation of binuclear complexes with octahedral geometry around each metal ion. For a better understanding of the response of complexes to biological activities, the stability constants, potential zeta and size of the complexes were determined. From the results, we can deduce that the complexes have more significant activities than their corresponding ligand. Moderate antioxidant activity recorded with both complexes, superior antibacterial and antifungal activities with Rh (III) complex with MIC value of 0.3125 mg. mL−1 and interesting anticancer activity towards Hep2 cells (IC50=13.77 μM) with Rh (III) and towards Hep2 (IC50=28.35 μM) and K562 cells (IC50=26.34 μM) with Cu (II) complex.

“…Table (3) shows also the magnetic susceptibility data and as it is observed, all the complexes has diamagnetic natures. The coordinated is suggested tetrahedral for Cd(II) and Zn(II) complexes [16] .The electronic spectra of the complexes in DMSO (Table (3)) exhibits intra-ligands n * band at 326 nm. Both the Cd(II) and Zn(II) complexes do not exhibit any d-d transition as they are d 10 system.…”

A new nitrogen sulphur Schiff base has been prepared from the condensation 1-(pyridin-4-yl) ethanone with 3-methylbenzyl hydrazinecarbodithioate leading the formation of new ligand 3methylbenzyl (2Z)-2-[1-(pyridin-4-yl)ethylidene]hydrazine carbodithioate (PE3MBC). The ligand was reacted with Cd(II) and Zn(II) metal salts to form new coordinated complexes. The new ligand and its metal complexes were characterized via various physico-chemical and spectroscopic techniques and conductivity, magnetic susceptibility of metal complexes based on the data analysis the metal complexes are expected to be tetrahedral in geometry.
