Academic researchers, R&D teams, teachers, students, policy makers and the media all rely on us to share knowledge that is reliable, accurate and cutting-edge. Introducing a new discovery about 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal, Quality Control of: (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal.
The planar dihydroxo-bridged [Cu2(dpyam)2(mu-OH) 2I2]·2H2O (1) and the roof-shaped trihydroxo-bridged [Cu2(dpyam)2(mu-OH) 3]Cl·3H2O (2) (in which dpyam = di-2-pyridylamine) dinuclear copper(II) compounds have been synthesized and their crystal structures determined by X-ray crystallographic methods. All of compounds are being centrosymmetric molecule. Compound 1 contains a dinuclear [I(dpyam)Cu(mu-OH)2Cu(dpyam)I]+ unit with a strictly planar CuO2 network, dihedral angle between the CuO2 planes of 180. Each copper(II) ion is in a tetrahedrally distorted square pyramidal coordination geometry of the CuN2O2I chromophore with a dihedral angle 19.3 between the CuN2 and CuO2 planes. In the dinuclear [(dpyam)Cu(mu-OH)3Cu(dpyam)]+ unit of compound 2, the triply bridged Cu(II) ions show a distorted square pyramidal coordination. The fifth apical ligand is a longer bonded bridging OH- group, at distance of 2.433(4) A?, which joins the basal CuN2O2 planes in a roof-shaped configuration with a dihedral angle of 142.5. The Cu-Cu distance is 2.803(7) A?.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Quality Control of: (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal.
