Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. In an article, published in an article, once mentioned the application of 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, is a conventional compound. this article was the specific content is as follows.Electric Literature of 499-40-1
Series of [Cu(I)dipyam(CO)X], [Cu(II)dipyam(CH3CO2)X] and [Cu(II) (dipyam)2(CH3CO2)]X complexes (dipyam = 2,2′-dipyridylamine; X = Cl(-), Br(-),I(-)) were synthesized and the structures of the title compounds were d etermined by X-ray diffraction methods. Crystallographic details for complexes [Cu(I)dipyam(CO)Cl] (1) and [Cu(II)dipyam(CH3CO2)Cl] (2) are as follows: complex 1, triclinic, space group P1- with a = 9.944(3), b = 9.450(3), c = 7.053(3)A, alpha = 69.50(2), beta = 91.81(2), gamma= 76.33(2)°, Z = 2; complex 2, triclinic, space group P1- with a = 10.093(3), b = 9.098(3), c = 7.444(2)A, alpha = 106.24(2), .bet a. = 96.91(2), gamma = 78.87(2)°, Z = 2. The dry carbonyl complexes are thermostable at 100°C or more, but their formation was reversible in solution even at room temperature. Thermal and chemical stabilities increase from the chloro to the iodo species. Among the acetatoderivatives the chloro and bromo mono-dipyam complexes were easily form ed, while the iodide gave preferentially the bis-dipyam complex. Each series of the complexes gave very similar IR spectra in the range 3800-250cm**-1. For the carbonyl derivatives the patterns of the far-IR 250-60 cm**-1 regions were shown and the nu(Cu-X) frequencies assigned.
