15 صفحه اولTwo-dimensional hydrogen-bonded polymers in the crystal structures of the ammonium salts of phenoxyacetic acid, (4-fluorophenoxy)acetic acid and (4-chloro-2-methylphenoxy)acetic acid
The structures of the ammonium salts of phen-oxy-acetic acid, NH4 (+)·C8H6O3 (-), (I), (4-fluoro-phen-oxy)acetic acid, NH4 (+)·C8H5FO3 (-), (II), and the herbicidally active (4-chloro-2-methyl-phen-oxy)acetic acid (MCPA), NH4 (+)·C9H8ClO3 (-)·0.5H2O, (III) have been determined. All have two-dimensional layered structures based on inter-species ammonium N-H⋯O hydrogen-bonding associations, which...
متن کاملTheoretical evaluation of medicinal properties for some of N-aryl-3-hydroxypyridine-4-ones derivative compounds
Today, the bidentate ligands 3-hydroxypyridin-4-ones (HPOs) as orally active iron chelating agents have been demonstrated to possess potential for treatment of some human diseases such as iron-overload in thalassaemic patients and malaria. In this research, a series of HPOs with different substitutes and position were theoretically invest
