4-Ethylthiosemicarbazide and its NH(1) derivatives have been prepared and confirmed by elemental analysis and 1H NMR spectra to produce diverse complexes with Co(II), Ni(II) and Cu(II) ions. The obtained complexes have been investigated based on elemental and thermal analyses, spectral (UV/VIS, ESR, mass) studies and magnetic measurements. The IR data reveal the presence of variable modes of chelation for the investigated ligands. The electronic spectra of the complexes as well as their magnetic moments provide information about geometries. The ESR spectra give evidence for the proposed structure and the bonding for some Cu(II) complexes. Thermal decomposition of some complexes ended with metal or metal oxide as a final product.read more

Synthesis, spectroscopic characterization and antimicrobial activity of mono-, bi- and tri-nuclear metal complexes of a new Schiff base ligand
TL;DR: In this paper, the structure of the dibasic Schiff base ligand was elucidated by analytical and spectroscopic tools (IR, 1 H and 13 C NMR spectra) which indicated that the coordinating sites are oxygen atoms of the phenolic OH groups, nitrogen atoms of azomethine groups and the oxygen atom of the ketonic group.

Preparation, spectral characterization and antimicrobial activity of binary and ternary Fe(III), Co(II), Ni(II), Cu(II), Zn(II), Ce(III) and UO2(VI) complexes of a thiocarbohydrazone ligand
TL;DR: A series of binary complexes of iron(III), cobalt(II), nickel, copper, zinc, cobalt, and cobalt have been synthesized by using the organic ligand, H 3 L, formed by the condensation of thiocarbohydrazide with 2-hydroxy-1-naphthaldehyde as mentioned in this paper.

Spectral and thermal studies for some transition metal complexes of bis(benzylthiocarbohydrazone) focusing on EPR study for Cu(II) and VO2
TL;DR: Electronic and magnetic data proposed the octahedral structure for all complexes under investigation, except VO(2+), is a square-pyramidal geometry and TG analysis for most complexes supports the absence of solvent molecules in or out the coordination sphere through the high thermal stability observed on the thermal curves for the investigated complexes.

Antioxidant activities of thiosemicarbazones from substituted benzaldehydes and N-(tetra-O-acetyl-β-d-galactopyranosyl)thiosemicarbazide
TL;DR: The antioxidant activity of these thiosemicarbazones was evaluated in vitro and in vivo, and it's shown that some of these compounds had significant antioxidant activity.
