One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 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, molecular formula is C12H22O11. In a Article，once mentioned of 499-40-1, 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
Ternary compounds formed between M , adenosine 5′-triphosphate , and bis(2-pyridyl)amine(bipyam) have been prepared The solid compounds are crystalline and have a stoicheiometry described by the formula M(Hatp)(Hbipyam)*nH2O (n = 2-9).X-ray powder diffraction patterns are similar.Potentiometric titrations in aqueous solution show the presence of two ionizable protons.Visible spectra suggest an octahedral co-ordination geometry.I.r. spectra indicated essentially the same type of metal-ligand interactions in all the complexes and show that Hatp(3-) co-ordinates to the metal through the oxygen atoms of the alpha, beta, and gamma phosphate groups.The ternary compounds where M = Mg(II)(1) or Ca(II)(2) have been studied by single-crystal X-ray diffration techniques and their molecular structures determined.The two species are isostructural and can be formulated as 22*9H2O (2).Both (1) and (2) crystallise in space group C2221 (Z = 4), with a = 22.734(3), b = 10.233(3), c = 30.997(4) Angstroem for (1) and a = 22.965(3), b = 10.154(3), c = 32.390(4) Angstroem for (2).X-ray diffraction data were collected on a Philips automatic diffractometer and the structures solved by direct methods using the SIR (Semi-invariant Representation) package and refined by full-matrix least squares to final R values of 0.111 and 0.124 (1 088 and 1 008 independent observed reflections) for (1) and (2) respectively.In the (4-) units the metal ions lie on a two-fold axis with an octahedral co-ordination geometry completed by the oxygen atoms of the alpha, beta, and gamma phosphate groups of two symmetry-related Hatp(3-) molecules.The co-ordination polyhedron of (1) is nearly regular but in (2) it is significantly distorted.The phosphate chains have a folded configuration in both (1) and (2).In both complexes there are no bonding interactions between the metal ions and the adenine base.The metal atoms of the (2+) cations are also located on two-fold axes while the six co-ordinated water molecules form hydrogen bonds with the phosphate chains.The Hbipyam(1+) molecules do not co-ordinate to the metal ions and are disordered around two-fold axes.Strong stacking interactions exist between Hbipyam(1+) and purine rings.
