HPLC of Formula: C12H22O11, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount. 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 patent, introducing its new discovery.
A new unique tetranuclear copper(II) complex doubly-bridged by thiocyanate anions [Cu4(mu1,3-NCS)6(dpyam) 4(O2CH)2(H2O)2 (dpyam = di-2-pyridylamine) has been synthesized and characterized by X-ray diffraction methods and magnetic measurements. The “outer” Cu ions, with a CuN3O(S, O) chromophore, have an axially elongated octahedral geometry. The basal plane of these outer Cu(II) ions consist of 2 nitrogen atoms of the dpyam ligand with Cu-N distances of 1.980(2) and 2.008(2) A?, one nitrogen atom of a bridging thiocyanate anion (Cu-N distance 1.961(3) A?) and an oxygen atom of a formate molecule (Cu-O distance 1.977(1) A?). The axial positions are occupied by an oxygen atom of a water molecule (Cu-O distance 2.518(1) A? and by a sulfur atom of a bridging thiocyanate anion at a semi-coordination distance of 3.048(1) A?. The “inner” Cu atoms, with a CuN4(S2) chromophore do also have an axially elongated octahedral geometry. The basal plane is formed by 2 nitrogen atoms of the dpyam ligand with Cu-N distances of 1.995(2) and 2.018(3) A? and two nitrogen atoms of two bridging thiocyanate anions (Cu-N distances 1.946(3), 1.976(3) A?). The axial positions are occupied by two sulfur atoms of two bridging thiocynate anions (Cu-S semi-coordinating distances are 2.875(1) and3.126(1) A?). Each Cu ion is bridged by two mu1,3-NCS anions (in an equatorial-axial bridging mode) forming in this way a zigzag tetranuclear unit. The magnetic susceptibility data of the compound have been investigated between 5 and 200 K. The compound shows a very weak antiferromagnetic interaction between the Cu ions, in agreement with the non-overlapping magnetic orbitals of each Cu ion.
