Like 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. In a document type is Article, introducing its new discovery.
Three novel compounds with bridging dichromate anions with the formulae [Fe(4,4?-bpy)2Cr2O7]n (1), [Co(4,4?-bpy)2Cr2O7]n (2), and [Ni(dpa)2Cr2O7]·H2O (3) (4,4?-bpy = 4,4?-bipyridine, dpa = 2,2?-dipyridylamine) have been synthesized and characterized. The isostructural compounds 1 and 2 belong to the monoclinic space group C2/c and have been shown to be three-dimensional polymers in which the dichromate anions connect neighboring layers formed by [M(4,4?-bpy)2]2+ (M = Fe, Co) units. Compound 3 is a metallacrown type compound, crystallizing in the monoclinic space group P2 1/n. Two chromate anions link two NiII centers forming a dinuclear entity. The uncoordinated oxygen atom of the dichromate anion forms a hydrogen bond with the N-H unit of dpa resulting in a two-dimensional network. Measurements of magnetic susceptibilities indicate the presence of antiferromagnetic interactions in 1 and 2 whereas the exchange coupling between the NiII ions in 3 is ferromagnetic. The IR and UV/Vis spectra of the above complexes have also been investigated. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: (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, you can also check out more blogs about499-40-1
