Application of 499-40-1, An article , which mentions 499-40-1, molecular formula is C12H22O11. The compound – (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 played an important role in people’s production and life.
[Mn(SCN)2(L)4/2] where L = py, gamma-pic, pyCH 2OH, py-NH-py (dpa) complexes have been prepared and studied by IR and UV-Vis spectroscopy, and X-ray crystallography. Electronic structures of the complexes were calculated using DFT method, and the descriptions of frontier molecular orbitals and the relocation of the electron density of the compounds were determined. The differences in acceptor properties of the used pyridine derivatives ligands were shown in the values of ligand field parameters determined from electronic spectra of the complexes. The magnetic properties revealed paramagnetic behavior with a weak ferromagnetic interaction and the van Vleck contribution for [Mn(SCN)2(py)4] (1), ideal paramagnetism for [Mn(SCN)2(gamma-pic)4] (2) and a weak antiferromagnetic interaction and diamagnetic contribution for [Mn(SCN) 2(pyCH2OH)2] (3).
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 499-40-1, help many people in the next few years., Application of 499-40-1
