“…Figure A,B shows the variations in ac conductivity as a function of the reciprocal of the temperature at selected frequencies 1 kHz and 1 MHz for a series of transition metal complexes of Cu (II), Co (II), Zn (II), and Cr (III) with N‐(4‐(2‐hydrazinyl‐2‐oxoethoxy)phenyl) acetamide (HL) as the ligand as well as the free ligand. The conductivity values for the metal complexes increase with increasing temperature, which indicates that they have a positive temperature coefficient and semiconducting properties . This increase in conductivity was attributed to the presence of a d‐d* transition in the metal, and this transition is possible in Cu (II), Co (II), and Cr (III) complexes.…”

A series of Cu (II), Mn (II), Co (II), Zn (II), Cr (III), and VO (IV) complexes with N-(4-(2-hydrazinyl-2-oxoethoxy)phenyl) acetamide (HL) were synthesized. The electrical properties of HL and its Cu (II), Co (II), Zn (II), and Cr (III) complexes were measured in the 298 to 373 K temperature range. The activation energy of each of these metal complexes was estimated. The conductivities of the metal complexes with HL increase with increasing temperature, revealing their semiconducting nature and potential for use in electronic devices. The complexes exhibited higher conductivities than HL itself. The kinetic parameters of these complexes, such as their stability constants (K c values) and Gibbs free energies (ΔG°), were investigated by using cyclic voltammetry. These parameters indicated that the prepared compounds exhibited better stability and adsorption properties than paracetamol (PA), which is the parent compound of these species. The complexes were more cytotoxic than the ligand towards MCF-7 human breast cancer cells.

“…The IR spectra of all complexes show ν(C N) bands at 1629-1590 cm −1 , [27] and the ν(C N) bands in the complexes are shifted to lower energy regions compared with the free ligands. The shift of this band towards the energy side is probably caused by an increase in the C N bond order owing to the coordination of the nitrogen with the copper atom.…”

The reaction of zinc(II) chloride, cadmium(II) chloride and bromide with 3-thiophene aldehyde thiosemicarbazone leads to the formation of a series of new complexes. They have been characterized by spectroscopic studies: infrared, (1)H NMR, and electronic spectra. The crystal structures of the compound [ZnCl(2)(3TTSCH)(2)] and [CdBr(2)(3TTSCH)(2)] have been determined by X-ray diffraction methods. For the complexes [ZnCl(2)(3TTSCH)(2)] and [CdBr(2)(3TTSCH)(2)], the central ion is coordinated through the sulfur, and for the complexes [CdCl(2)(3TTSCH)], [CdBr(2)(3TTSCH)] the ion is coordinated through the sulfur as well as azomethine nitrogen atom of the thiosemicarbazone. In addition, fungistatic and bacteriostatic activities of both ligand and complexes have been evaluated. Cadmium(II) complexes have shown the most significant activities.
