A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 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.

CATION DISTORTION ISOMERISM IN THREE FIVE-CO-ORDINATE DIETHYLENETRIAMINE(DI-2-PYRIDYLAMINE)COPPER(II) COMPLEXES
The crystal structures of three X2*nH2O (dien = diethylenetriamine, bipyam = di-2-pyridylamine) complexes have been determined by R-ray crystallographic methods, where X = Cl(1-), n = 2 (1); X = ClO4(1-), n = 1 (2); X = NO3(1-), n = 0 (3).All three crystallise in the monoclinic, space group P21/c with Z = 4; in (1) a = 7.78(2), b = 9.75(3), c = 28.01(5) Angstroem, and beta = 115.0(5) deg; in (2) a = 15.683(5), b = 7.621(5), c = 21.044(9) Angstroem, and beta = 121.42(2) deg; and in (3) a = 12.2011(5), b = 16.052(6), c = 9.851(4) Angstroem, and beta = 90.76(2) deg.All three structures were solved by heavy-atom techniques and successive Fourier syntheses; all three complexes involve a distorted five-co-ordinate CuN5 chromophore, whose stereochemistry ranges from distorted square pyramidal in (1), through an intermediate geometry in (2), to a distorted trigonal-bipyramidal stereochemistry in (3).The three stereochemistries represent individual structures in the pathway of the Berry twist and represent cation distortion isomers of the (2+) cation.The angular changes in the CuN5 stereochemistry are paralelled in the electronic reflectance spectra of the three complexes and in the calculated crystal-field energy level of the copper(II) ion.
