The article conveys some information:
To broaden the limited knowledge concerning the zinc(II) coordination chem. with amino alcs., reactions of [Zn(quin)2(H2O)] (quin- = quinaldinate, C10H6NO2) with 3-amino-1-propanol (3-apOH, C3H9NO) and N-methylaminoethanol (N-maeOH, C3H9NO) were studied. The starting material, zinc(II) with two quinaldinates coordinated in a bidentate chelating mode, provides a structurally rigid core with two sites available for interaction with amino alc. ligands. When the reactions were carried out in acetonitrile in autoclaves at 105°, an unforeseen decomposition of amino alcs. to ammonia took place. This was accompanied by crystallization of an ammine complex [Zn(quin)2(NH3)] (1). Mass spectrometry of the gaseous phases confirmed unambiguously the presence of ammonia in such reaction mixtures The desired complexes with coordinated amino alcs. could be obtained in good yield by carrying out the reactions at room temperature and/or in various solvents. Two novel amino alc. complexes were prepared, [Zn(quin)2(3-apOH)] and [Zn(quin)2(N-maeOH)]. The 3-apOH ligand was coordinated to zinc(II) in a monodentate manner via the amino nitrogen. The 3-apOH complex crystallizes as an acetonitrile (2a), ethanol (2b), 2-propanol (2c) or water (2d) solvate. The conversion of 2a to 2d was monitored by IR spectroscopy. In [Zn(quin)2(N-maeOH)] (3), the N-maeOH ligand was coordinated in a bidentate chelating manner through both functional groups. DFT calculations were performed on the isomers of [Zn(quin)2(3-apOH)] and [Zn(quin)2(N-maeOH)], which differ in the binding modes of their amino alc. ligands. Complete characterization of all compounds by x-ray structure anal., IR spectroscopy and NMR spectroscopy is presented. In the experiment, the researchers used many compounds, for example, 3-Aminopropan-1-ol(cas: 156-87-6Related Products of 156-87-6)
3-Aminopropan-1-ol(cas: 156-87-6) belongs to anime. The methylamines occur in small amounts in some plants. Many polyfunctional amines (i.e., those having other functional groups in the molecule) occur as alkaloids in plants—for example, mescaline, 2-(3,4,5-trimethoxyphenyl)ethylamine; the cyclic amines nicotine, atropine, morphine, and cocaine; and the quaternary salt choline, N-(2-hydroxyethyl)trimethylammonium chloride, which is present in nerve synapses and in plant and animal cells.Related Products of 156-87-6
