“…A tridentate chelating + m 2 -bridging mode has also been reported for neutral tren [20][21][22][23]. The m 3 -tren mode always involves the coordination of the three terminal amino groups to three metallic centers such as Li I [14], Ag I [24,25], Mn II [26], Cu II [27][28][29], Cd II [30], Ti IV or Zr IV [31]. The highest m 4 -bridging tetradentate role has only been observed for a K I -polymeric cation found in the structure of [K 2 (m 4 -tren) 2 ] n (H 3 O) 4n [Ru III Cl 6 ] 2n Á4nH 2 O [32].…”

“…Schiff's bases considered as an important class of compounds in both the medical, pharmaceutical, and biological fields. They were also found to exhibit a broad range of biological activities, including antifungal, antibacterial, antimalarial, antiproliferative, antiinflammatory, antiviral, and antipyretic properties …”

The new Schiff base 1‐[(2‐{1‐[(dicyclohexylamino)‐methyl]‐1H‐indol‐3‐yl}‐ethylimino)‐methyl]naphthalen‐2‐ol (HL) was prepared from 1‐{[2‐(1H‐Indol‐3‐yl)‐ethylimino] methyl}‐naphthalen‐2‐ol and dicyclohexyl amine. From this Schiff base, monomeric complexes [M (L)n (H2O)2 Cl2] with M = Cr, Fe, Mn, Cd, and Hg were synthesized and characterized based on elemental analysis (EA), FT‐IR, mass(MS), UV‐visible, thermal analysis, magnetic moment, and molar conductance. The results showed that the geometrical structural were octahedral geometries for the Cr(III) and Fe(III) complexes, square planer for Pd(II) complex, and tetrahedral for Mn(II), Cd(II), and Hg(II) complexes. Kinetic parameters such as ΔE*,ΔH*, ΔG*, and K of the thermal decomposition stages were calculated from the TGA curves using Coats‐Redfern method. Additionally, density functional theory (DFT) was applied for calculations of both electronic structure and spectroscopic properties of synthesized Schiff base and its complexes. The analysis of electrostatic potential (EPS) maps correlates well with the computed energies providing on the dominant electrostatic nature of N‐H‐‐‐O interactions. The biological activities had been tested in vitro against Staphylococcus aureus, Pseudomonas aeruginosa, as well fungi like Penicillium expansum, Fusarium graminearum, Macrophomina phasealina, and Candida albicans bacteria in order to assess their antimicrobial potential.

“…[1][2][3] In recent years, there has been considerable interest in the chemistry of transition metal complexes of thiosemicarbazone ligands, primarily because of their bioinorganic relevance. 4 In the solid state, these thiosemicarbazones exist in the thione form and in solution they tautomerize into the thiol form.…”

The complexation reaction between salicylaldehyde thiosemicarbazone, abbreviated as STSC, with Cu(II) ion was studied in binary mixtures of methanol-1,4-dioxane using UV-Vis spectrophotometric and conductometric methods at different temperatures. The formation constants (K f ) for the 1:1 complex, Cu(II)-STSC, were calculated from computer fitting of the absorbance and molar conductance data against various concentrations ratios (c M :c L or c L :c M ) in different binary solvent mixtures. A non-linear correlation was observed for the variation of log K f for the complex against the solvent compositions. Various thermodynamic parameters (ΔH, ΔS and ΔG) for the formation of the Cu(II)-STSC complex were also determined from the temperature dependence of the formation constants (K f ). The results showed that the complexation reaction is affected by the nature and composition of the mixed solvents.
