In 2017,Colak, Alper Tolga; Gunay, Handan; Temel, Ersin; Buyukgungor, Orhan; Colak, Ferdag published 《Synthesis, crystal structures, characterization and antimicrobial activities of 5-hydroxyisophthalate complexes》.Transition Metal Chemistry (Dordrecht, Netherlands) published the findings.Quality Control of 2-(2-Hydroxyethyl)pyridine The information in the text is summarized as follows:
Two 5-hydroxyisophthalate complexes of nickel(II), formulated as [Ni(μ-Hhip)(2-hepy)2]n (1) and [Ni2(μ-Hhip)2(dap)4]n (2) (H3hip = 5-hydroxyisophthalic acid, 2-hepy = 2-(2-hydroxyethyl)pyridine, dap = 1,3-diaminopropane), have been synthesized and characterized by chem. and spectroscopic methods. The mol. structures of the complexes have been determined by single-crystal x-ray diffraction anal. The Ni(II) centers have distorted octahedral geometries in both crystals. Furthermore, both complexes have 1D chain structures in which the individual chains are linked together via hydrogen bonds to give 3D frameworks. Evaluation of the complexes by the agar diffusion method showed that they have weak antibiotic activities against the tested microorganisms. In the part of experimental materials, we found many familiar compounds, such as 2-(2-Hydroxyethyl)pyridine(cas: 103-74-2Quality Control of 2-(2-Hydroxyethyl)pyridine)
2-(2-Hydroxyethyl)pyridine(cas: 103-74-2) belongs to pyridine. When pyridine is adsorbed on oxide surfaces or in porous materials, the following species are commonly observed: (i) pyridine coordinated to Lewis acid sites, (ii) pyridine H-bonded to weakly acidic hydroxyls, and (iii) protonated pyridine. At high coverage, physisorbed pyridine and protonated dimers can also be observed.Quality Control of 2-(2-Hydroxyethyl)pyridine
