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.

Two-dimensional hydrogen bonded sheet structures in nickel(II)- and zinc(II)-2,2?-dipyridylamine-azido complexes
One-pot reactions of metal acetate, 2,2?-dipyridylamine (dpa) and NaN3 in a 1:2:2 ratio in aqueous-acetonitrile solutions result in mononuclear complexes of the type [M(dpa)2(N3) 2] ? H2O [M = Ni (1), Zn (2)]. Structural analyses reveal that both the metal centres adopt distorted octahedral MN6 environments coordinated through four N atoms of two dpa units and two azide N atoms as terminal ligands – the latter occupying mutual cis positions. The crystal packing shows that the mononuclear units self-assemble through hydrogen bonds to afford infinite two-dimensional (2D) sheets. Additionally, the pyridyl planes of adjacent sheets are engaged in face-to-face pi?pi and C-H?pi interactions leading to a 3D supramolecular continuum. Complexes 1 and 2 exhibit high-energy intraligand 1(pi-pi*) fluorescence and intraligand 3(pi-pi*) phosphorescence in glassy solutions (DMF at 77 K). A band (374 nm) observed in their solid-state emission spectra is an excimeric emission originating from an aromatic pi?pi interaction. The role of dpa is highlighted in controlling crystalline aggregation and in arousing luminescence characteristics.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.name: (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.
