The synthesis and solid state structural, spectral and electrochem. solution characterization of [Cu(L)(acpy)]ClO4鑱?strong>1 and [Cu(L)(NO3)] 2 [where L = N’-[(E)-phenyl(pyridin-2-yl)methylidene]thiophene-2-carbohydrazide and acpy = 2,6-Diacetylpyridine] were done by elemental anal., UV-visible, FTIR, electrochem. techniques (CV and DPV) and EPR spectroscopy. The single crystal structures were solved by the x-ray diffraction technique. In complex 1, copper ion is in a distorted octahedral environment. The geometry of copper(II) in complex 2 is distorted square pyramidal (锜?= 0.201). The mono deprotonated, HL ligand act as a tridentate to a copper(II) ion. On the basis of d. functional theory (DFT) calculation, the electronic excitations involve transitions mainly from metal ligand bonding mostly the 浼?LUMO within the dominant Cu dxy character and to 浼?LUMO+1. EPR spectra for polycrystalline samples showed the copper(II) hyperfine features as well as half-field signal which are appropriate for 铻朚s = 鍗? of dimers. Presence of half-field signal in 1 is due to solid-solid interaction (intra-mol.) where as in 2 the nature of interaction is intra-mol. The antioxidant superoxide measurements show that the both complexes 1 and 2 behave as superoxide mimic in alk. nitro blue tetrazolium chloride assay. In the experiment, the researchers used many compounds, for example, Phenyl(pyridin-2-yl)methanone (cas: 91-02-1Quality Control of Phenyl(pyridin-2-yl)methanone).
Phenyl(pyridin-2-yl)methanone (cas: 91-02-1) belongs to pyridine derivatives. Pyridine has a conjugated system of six 锜?electrons that are delocalized over the ring. The molecule is planar and, thus, follows the H鐪塩kel criteria for aromatic systems. Pyridine derivatives are also useful as small-molecule 浼?helix mimetics that inhibit protein-protein interactions, as well as functionally selective GABA ligands.Quality Control of Phenyl(pyridin-2-yl)methanone
