Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments. Related Products of 108-47-4, Name is 2,4-Dimethylpyridine, belongs to chiral-nitrogen-ligands compound, is a common compound. Related Products of 108-47-4Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. In an article, authors is Singh, Kuldeep, once mentioned the new application about Related Products of 108-47-4.

A series of complexes with general formula M(Xan)2L2 (M = Ni(II), Xan = O-amyldithiocarbonato, L = 3-methylpyridine, 2,4-; 3,4-; 3,5-dimethylpyridines and 2,4,6-trimethylpyridine) have been synthesized and characterized by elemental analysis and various physico-chemical techniques such as magnetic susceptibility measurements, conductivity measurements, UV-Visible, Infrared spectral data. On the basis of electronic spectra and magnetic susceptibility measurements, an octahedral geometry has been proposed for all the complexes. IRspectral data shows that the substituted pyridines in all these complexes coordinate to the metal ion through nitrogen atoms occupying fifth and sixth axial positions where as O-alkyldithiocarbonate act as monoanion bidentate ligand and occupy the planar positions of octahedral structures. The X-ray diffraction analysis of one of the adducts bis(O-amyldithiocarbonato) bis(3,5-dimethylpyridine) nickel(II) is also investigated. The complex crystallizes in the monoclinic space group P21/c with unit cell parameters a = 9.167(2) A, b = 18.255(4) A, c = 9.299(2) A and beta = 103.47(2). The dihedral angle between dithio-groups and the pyridine ring is 88.9(1). The crystal structure of the molecule is stabilized by pi-pi interactions. Springer Science+Business Media New York 2012.
