Avcu Altiparmak, Elif; Yazar, Sibel; Ozdemir, Namik; Bal-Demirci, Tulay; Ulkuseven, Bahri published an article in 2021. The article was titled 《Supramolecular Ni(II) complex aggregates with a circular linkage of intermolecular multi-hydrogen bonding frameworks based on thiosemicarbazone, and a Cu(II) complex: Synthesis, structural, DFT, electrochemical and antioxidant studies》, and you may find the article in Polyhedron.Safety of 2-Hydroxy-4-methoxybenzaldehyde The information in the text is summarized as follows:
Copper(II) and nickel(II) mixed ligand complexes were synthesized from 4-methoxysalicylaldehyde-N-phenyl-thiosemicarbazone and 3,5-lutidine. The structures of the complexes were characterized by elemental anal., IR, UV, 1H NMR and ESI-MS spectra, together with magnetic susceptibility measurements. Complex I has a distorted square planar geometry, with coordination of azomethine nitrogen, thiolate sulfur, phenolate oxygen and pyridyl nitrogen atoms, by the single-crystal x-ray diffraction technique. Quantum chem. DFT calculations also were carried out using the DFT/HSEH1PBE method with the cc-pVDZ basis set for C, H, N, O and S atoms, and the LANL2DZ basis set for the metal atom. The antioxidant activities of the ligand and its metal complexes were studied by CUPRAC and DPPH assays and calculated as their trolox equivalent antioxidant capacities (TEAC). Electrochem. properties were performed with cyclic voltammetry and square wave voltammetry. Both the ligand and its metal complexes have antioxidant capacity. In the experiment, the researchers used many compounds, for example, 2-Hydroxy-4-methoxybenzaldehyde(cas: 673-22-3Safety of 2-Hydroxy-4-methoxybenzaldehyde)
2-Hydroxy-4-methoxybenzaldehyde(cas: 673-22-3) is the main component of root bark essential oil of Periploca sepium Bunge. It is a potential tyrosinase inhibitor present in African medicinal plants. 2-Hydroxy-4-methoxybenzaldehyde was used in the synthesis of Schiff base ligand.Safety of 2-Hydroxy-4-methoxybenzaldehyde
