“…Metal-organic frameworks (MOFs) display fascinating structures [1][2][3][4][5] and usefiil properties in photoelectrical [6,7], magnetic [8], catalytic [9], and porous materials [10]. Although some results have been achieved [11][12][13], it is still a challenge to rationally and predictably assemble MOFs.…”

Two cadmium complexes, {[Cd(a-ptt)(ptt)]-H2O¡,, (1) and [Cd(a-Hmtt)2(SO4)H2O]-CH3OH (2), have been prepared based on 4-amino-3-(4-pyridine)-5-mercapto-1,2,4-triazole (a-Hptt) and 4-amino-3-methyl-5-mercapto-1,2,4-triazole (a-Hmtt), respectively. In 1, amino-triazole ligand aHptt can partly be deaminated and transformed into 3-(4-pyridine)-5-mercapto-triazole (Hptt) under hydrothermal conditions. X-ray diffraction analysis reveals that I exhibits an unusual 2-D lampshade-type layer structure in which the amino ligand a-ptt and the deamination ligand ptt display eATo-tridentate bridging and bidentate bridging, respectively. Complex 2 is mononuelear and further assembled into a 3-D supramolecular architecture via non-covalent interactions. Complexes 1 and 2 were characterized by elemental analyses, IR, and thermogravimetric analyses. Furthermore, solidstate luminescent properties of 1 and 2 have also been investigated.

“…The results of the electrochemical analysis confirmed by the current potential data of peak separation (∆E) and the peak current ratio (Ipa/Ipc) of the (Mn, Cu and Cd) complexes that the charge transfer processes are irreversible, the systems are diffusion controlled and also adsorptive controlled, and the charge transfer rate constant of metals in their complexes are less than those in their metal salts at identical experimental conditions due to the coordination of metal with methionine [11,12]. The voltammetric study of manganese complex with saccharine was studied to determine the redox current peaks of the complex as irreversible process at different pH and concentrations [13].…”

The electrochemical effect of different temperatures on sodium saccharine in blood medium using modified working electrode CnT/GCe by cyclic voltammetry Abstract sodium saccharin (nasc) was studied as a chemical compound used for diabetic patients as a replacement for natural sugar. the study was focused on the effect of different temperatures on nasc in human blood medium using cyclic voltammetric technique at modified glassy carbon electrode (Gce) with carbon nanotubes (cnt) as working electrode (cnt/Gce). the physical chemistry functions were studied for the activated values in terms of enthalpy (∆H*), free energy (∆G*) and entropy (∆s*) for redox current peaks of nasc in blood medium at both electrodes, Gce and cnt/Gce using eyring equations. Also, the study included the determination of the activation energy (ea*) determined by Arrhenius equations for the redox current peaks of nasc to compare values obtained by Gce and cnt/Gce. it was found that the values of thermodynamic functions were different due to the oxidation -reduction reaction of nasc in blood medium which reacts with many complex compound with the component of the blood especially hemoglobin as ferric and ferrous ions. the oxidative stress of nasc in blood medium appeared clearly in voltammogram.

“…‐ Methionine, as reported earlier, can bind with oxygen donor site of carboxylic acid and carbonyl functional group, in some square planar it is found that ‐S atom is coordinated with Ag and literature shows formation of Pt (II) complex coordinated with S and N donor sites . Methionine has also been reported to bind from its oxygen donor site of carboxylic acid as well as nitrogen donor site of amino group It is evident from previous synthetic approaches that not only 8‐hydroxyquinoline is known for it's potential as an antioxidant property, methionine is also displayed a vital role as an antioxidant in different cellular processes and connecting different reversible oxidation and reduction reactions of protein .…”

The purpose of this investigation is to synthesize mixed ligand complexes of first, second, and third row transition metals including Cr (III), Mn (II), Fe (III), Co (II), Ni (II), Cu (II), Zn (II), Cd (II) and Pb (II) with L 1 = 8-hydroxyquinoline and L 2 = DLmethionine. Newly synthesized metal complexes have been characterized by UV-Visible, IR, mass spectrometry and microanalytical techniques such as conductance measurement, elemental analysis, and melting point. Synthetic mixed complexes were also screened for antioxidant activity.
