This article details the synthesis of new Girard‐T reagent ligands. Condensation of 2‐hydroxyacetophenone or 2‐acetyl‐thiophene with Girard‐T reagent results in new hydrazone ligands. The interaction of these Girard‐T hydrazones with transition metal chlorides, like Au (III), Ru (III), Pd (II), and Pt (II), produces different complexes. Elements and spectrum analyses (IR, UV–Vis, EI‐mass, and 1H NMR) were used to characterize the isolated solid complexes, as well as conductimetric and magneto‐chemical studies. Metal complexes can have different geometrical configurations, including square planar and octahedral coordination. The DMOL3 method, which is a part of the Material Studio package, was also utilized for structure optimization. Horowitz–Metzger and Coats–Redfern methods were utilized to calculate the various thermodynamic and kinetic parameters. The ligands and the complexes of their metal were evaluated for anticancer activity against carcinoma cervix (Prostate) and the mammary gland female breast (MCF‐7) cell line having cancer, with promising results. Among these compounds, the Ru (III) and Pt (II) complexes' anticancer activity against (MCF‐7) cell lines, comparable with that of 5‐fluorouracil were carried out and their interactions were performed by molecular docking simulations against MCF‐7 (PDB ID: 3W2S) receptor.

“…Schiff based macrocyclic complexes are a prominent class of molecules that have received a lot of attention due th their wide applications [19]. Ligands and complexes of this type are used as sensors, catalysts, DNA binding/cleavage agents, anticancer agents and models of metalloenzyme reaction centers, dioxygen transport and photosynthesis and as a catalyst for RNA cleavage etc [20][21][22]. In this work, we reported the template synthesis, characterization and microbial study of Ni(II) complexes of macrocyclic Schiff base ligands (2,3,9,10-tetraphenyl-1,4,8,11-tetraazacyclotetradeca-1,3,8,10-tetraene (BDP), 2,4,10,12-tetramethyl-1,5,9,13-tetraazacyclohexadeca-1,4,9,12-tetraene (ADP) and 2,3,9,10-tetramethyl-1,4,8,11-tetraazatetradeca-1,3,8,10-tetraene (DDP)).…”

Ni(II) complexes of Schiff’s base macrocyclic ligands i.e. 2,3,9,10-tetraphenyl-1,4,8,11- tetraazacyclotetradeca-1,3,8,10-tetraene (BDP), 2,4,10,12-tetramethyl-1,5,9,13 tetraazacyclohexadeca-1,4,9,12-tetraene (ADP) and 2,3,9,10-tetramethyl-1,4,8,11 tetraazatetradeca-1,3,8,10-tetraene (DDP) have been synthesized. All these synthesized complexes have been characterized by elemental analysis, molar conductance, magnetic susceptibility measurement, IR and UV-Visible spectral studies. On the basis of elemental analysis, the complexes have been found to have the general composition Ni(Lig)X2 where Lig = BDP, ADP, DDP and X = Cl-, SO42- and NCS-. Molar conductance of complexes has been measured in DMSO solvent and the obtained values indicate non-electrolytic nature of all complexes i.e. counter ions are present inside the coordination sphere. Magnetic moments and electronic spectral data suggested six coordinated octahedral geometry for the Ni(II) complexes. The ligand field parameters have been calculated for metal complexes by using various energy level diagrams. In vitro synthesized complexes have been examined against the growth of the some plant pathogenic fungi in order to assess their microbial properties.
