2-Acetylpyridine-4-phenyl-3-thiosemicarbazone (APPT) ligand was incorporated onto Amberlite XAD-2 resin through an azo spacer and characterized by FTIR spectroscopy, elemental analysis, TGA, and SEM analysis. The synthesized resin was used for the preconcentration of Pb(II), Zn(II), Co(II), Ni(II), Cu(II), and Cd(II) ions. The sorbed metal ions were eluted with 10 mL of 2.0 mol L−1 HCl and determined by microsample injection coupled flame atomic spectrometry (MIS-FAAS).

In this study, the stability constants (logB11) of twenty-eight new complexes between several ion metals and thiosemicarbazone ligands were predicted on the basis of the quantitative structure property relationship (QSPR) modeling. The stability constants were calculated from the results of the QSPR models. The QSPR models were built by using the multivariate least regression (QSPRMLR) and artificial neural network (QSPRANN)

Tetra-coordinated nickel(II) complexes of two ONS (1, 2) and seven ONN (3a–3g) chelating 2-hydroxy3-methoxy-benzaldehyde thiosemicarbazones were synthesized. The dibasic ligands and complexes bearing PPh 3 as a coligand were characterized by means of analytical and spectroscopic data. Cytotoxic activities of the ligands and nickel(II) complexes were determined using the MTT assay in vitro against MDCK cells, and then all the compounds were tested on influenza virus replication by plaque assays. The compounds showed GI 50 values varying from concentrations of 15.9 up to 161.

Two Pd(II) and Zn(II) complexes with an anthracene-based thiosemicarbazone (H5cATSC) have been conveniently prepared. Reaction of the ligand with relevant metal precusors yields the complexes Pd-5cATSC and Zn-5cATSC which have been then structurally determined by X-ray crystallography. The results reveals that the complexes are of mononuclear structure and adopts square-planar and tetrahedral geometries around the central metal ions.

New hexa-coordinated binuclear Ru(II) thiosemicarbazone complexes of the type {[(B)(EPh3)(CO)ClRu]2L} (where, E = P or As; B = PPh3 or AsPh3 or pyridine; L = mononucleating NS donor of N-substituted thiosemicarbazones) have been synthesized and characterized by elemental analysis, FT-IR, UV–vis and 31P{1 H} NMR cyclic voltammetric studies. The DNA-binding studies of Ru(II) complexes with calf thymus DNA (CT-DNA) were investigated by UV–vis, viscosity measurements, gel-electrophoresis and fluorescence spectroscopy.

The analysis of IR, UV-vis, MS, 1H-NMR, 13C-NMR, COSY, and HSQC illustrated that HL1, HL2, HL3 were bidentate ligands and bound to the metal through the imine nitrogen and the net negatively charged sulfur in thiol form. Furthermore, it was demonstrated that the chelating ligands in the Pt(II) complexes were in the trans configuration.

Pyrenyl core was incorporated into a thiosemicarbazone ligand through condensation reaction between 1-pyrandehyde and relevant thiosemicarbazide. The complexation of the ligand with palladium ion occurred readily in aqueous solution with the aid of a base (triethylamine). Physical methods such as infrared spectroscopy, nuclear magnetic resonance spectroscopy, mass spectrometry, and X-ray single crystal diffraction revealed that the ligand and its palladium complex have been successfully synthesized.
